  • Active sonar reverberation suppression based on beam space data normalization

    Reverberation is the main interference in active sonar detection, due to its special properties, reverberation suppression is a difficult problem in active sonar signal processing. In this paper, the method of reverberation suppression is studied, and a new method based on the normalization of the beam space data is proposed. The basic idea of this method is to normalize the time waveform of the beam space, and then carry out the subsequent matched filtering and port-starboard discrimination. This method can reduce CFAR detection probability under reverberation background, remove the interference of own ship, and does not affect the performance of the subsequent signal processing, compared with the method of normalization after matched filtering, this algorithm has low false alarm probability and engineering practicability, Shallow sea experimental data of active towed array show that the method is effective.

  • The reverberation suppression in wideband diver detection sonar

    The reverberation suppression is the foundation of target detection in diver detection sonar. The reverberation caused by the sea bottom is generally strong. Conventional methods with only amplitude cannot remove these reverberations completely because of the random temporal fluctuation of the signal amplitude, which causes false alarms especially in the small target detection. Spatiotemporal stability derived from the variance of phase difference which is independent from the amplitude has been adopt to the reverberation suppression for narrow band signals in diver detection sonar systems, which are more complicated in wide band sonar. Wideband signals have the predominance of narrow band signals, because of the better resolution in range and azimuth. To access the high resolution and low false alarm simultaneously, the reverberation suppression combining amplitude with phase difference in wide band diver detection sonar needs to be achieved. So this paper proposed an improved method to suppression the reverberation for the wideband sonar system. The spatiotemporal stability estimation is proposed to be achieved based on the wavelet cross spectrum after wideband split-beam forming. The estimation algorithm in the wavelet domain is discussed. And the experiment results are given at last.

  • A detection method based on sonar image for underwater pipeline tracker

    The surveillance and inspection of underwater pipelines are carried out by operators who drive a remotely operated underwater vehicle (ROV) with camera mounted on it. However in very turbid water, the camera can not capture any scene, even with auxiliary high-intensity light. In this case the optical detection devices are unable to complete the surveillance task In recent years, forward looking sonar is widely applied to the underwater inspection, which is not subject to the influence of light and turbidity. So it is suitable for the inspection of pipelines. But the dynamic change of ROV by the water flow will lead to the target to escape from the sonar image easily. In addition, the sonar image is with high noise and low contrast. It is difficult for the operator to identify the pipeline from the images. Moreover, the surveillance of underwater pipelines is tedious and time consuming and it is easy to make mistakes due to the fatigue and distraction of the operator. Therefore, the study focuses on developing image processing algorithms to detect the pipeline automatically. By using the proposed image processing method, firstly the images are enhanced using the Gabor filter. And then these images are applied for an edge detector. Finally the parameters of the pipeline are calculated by Hough transform. To reduce the search area, the Kalman filter is explored to predict the parameters of the pipeline on the next image. And the experiment is shown the vision system is available to the surveillance of underwater pipelines.

  • Real-time SAS processing for high-arctic AUV surveys

    Interferometrie Synthetic Aperture Sonar (InSAS) delivers ultra-high range independent image resolution with 3D seabed bathymetry at higher Area Coverage Rates (ACRs) and resolution than can be achieved with traditional physical aperture limited sidescan sonar. The along track resolution is achieved by synthesising the required aperture length by moving a physical aperture while sampling the field of view. The result is a compact power efficient solution ideally suited for use on Autonomous Underwater Vehicles (AUV) and towed platforms. This paper will discuss the advantages of SAS as a tool for search and survey applications, including a detailed analysis of the processing and data handling workflow. Example workflow steps include SAS processing (image and bathymetry formation), georeferencing, mosaicing, data formatting, map generation, data storage, data recovery and data visualization. In August 2014, Kraken Sonar Systems participated in the Victoria Strait Expedition to search for the missing ships from Sir John Franklin's doomed Arctic expedition. The expedition team used a variety of sonar survey tools, including a Kraken InSAS system, installed onboard the Arctic Explorer AUV owned by Defense Research and Development Canada (DRDC). Results from the search will be presented, as well as a discussion of the application of AUVs for high-arctic seabed survey.

  • Disguised Bionic Sonar Signal Waveform Design With its Possible Camouflage Application Strategy for Underwater Sensor Platforms

    The covertness of an active sonar is a very important issue and the sonar signal waveform design problem is studied to improve covertness of the system. Many marine mammals produce call pulses for communication and echolocation, and existing interception systems normally classify these biological signals as ocean noise and filter them out. Based on this, a disguised sonar signal waveform design approach with its camouflage application strategy for underwater sensor platforms is proposed by utilizing bio-inspired steganography. We first construct bionic sonar signal waveforms which are very close to the true whale whistle, and then embed these constructed bionic sonar signal waveforms into the true whale call trains to hide the real sonar signal waveforms. According to the time-frequency structure of the true whale whistle, a bionic sonar signal model is established to generate the proposed sonar signal waveforms. A single sonar signal is used to measure the range of the target and a combination of two sonar signals is utilized for measuring its speed. A high-performance range and speed measurement algorithm is deduced in detail. Based on the constructed signal waveforms and the characteristics of false killer whale call trains, a camouflage application strategy is designed to improve the camouflage ability of the sonar signal sequence. Finally, simulation results are provided to verify the performance of the proposed method.

  • The application of NDT algorithm in sonar image processing

    Image matching technology is an important part of image processing technology. In this paper, the normal distributions transform (NDT) image matching algorithm and its application in the sonar image processing is studied. The NDT algorithm is based on a probability model. It calculates the coordinate of the image of the target point instead of the grey value, and this speeds up the sonar image matching process. Previously, before image matching was available, per-processing of the sonar image was necessary. The research of pre-processing of sonar imaging concerns noise reduction and image segmentation of the sonar image. Several classical methods of sonar image noise reduction are studied. The advantages and disadvantages of each method are analyzed. Based on a kind of DSP chip, the NDT image matching algorithm is achieved.

  • The influence of marine biological noise on sonar detection

    Ocean ambient noise is usually considered as an interfering background for underwater devices. As a key component of ocean ambient noise, marine biological noise also has a serious effect on sonar detection performance. It is found that marine mammal noise has a wide frequency band, with the energy mainly concentrating on low frequency band 10 ~ 500 Hz and medium frequency band 500 Hz ~ 25 kHz, which therefore significantly increases ocean ambient noise. The influence of marine biological noise on sonar detection is simulated with a RAM transmission model. Simulation results reveal that marine mammal noise brings about a drop of the detection range of surface targets from 25 km to 2~10 km. Moreover, the source levels of false killer whales, bottlenose dolphins and sperm whales are all very high, and can propagate over long distances. The frequency band and time duration of these marine mammal noises resemble an active sonar signal, which would result in a higher false alarm rate.

  • Study on bistatic scattering characteristics of an ellipsoidal object

    Multistatic sonar has the characteristics of traditional passive and active sonar, including good concealment performance, strong anti-interference ability, far-distance reaction, high positioning accuracy, the advantages of easy-to-optimization design, etc. Multistatic sonar will be the important direction for future development of active sonar. About the scattering characteristics of multistatic sonar targets, this paper establishes a bistatic sonar scattering model with ellipsoidal targets as an example. The variation of the target intensity with the incident angle is calculated under the condition of bistatic sonar. The concept of the equivalent incident angle is introduced to calculate the variation of the target intensity with it, and analyze the scattering characteristics. All the results provide theoretical basis for the underwater targets positioning, detection and identification by the multistatic sonar system.
