  • Self-adaptive frequency agility realized with FPGA

    Searching radar or surveillance radar has to resist diversified jamming; self- adaptive frequency agility is an important and effective function for radars to resist jamming. The detailed steps to achieve this function are described, and the function is realized with FPGA using hardware description language, the validity is proved by on-line sampling and simulation. The self-adaptive frequency agility module can analyze the type of jamming to select transmitting frequency to avoid the frequencies which have interference, under frequency diversity and fixed frequency, respectively. The practical application on a searching radar shows that the module has good real-time and anti-jamming capacity.

  • Angle measurement in the presence of mainbeam interference

    The problem of reducing interference impinging on an antenna array when the sources lie in the main beam is addressed. Adaptive antenna arrays are incorporated to form adapted sum and difference beams in which the interference signals are suppressed. Monopulse error curves are then obtained, providing the necessary distortion correction curves across the entire mainbeam tracking angle region. New Cramer-Rao (C-R) bounds on the angle estimation error are derived with generalized assumptions on the signal amplitude and phase. The bounds previously derived by others are valid under different conditions. With these generalized assumptions on the signal characteristics, a Monte Carlo simulation is performed, based on the estimation procedure presented, to determine the angle estimation error. These errors are compared with the C-R bounds. Good performance is shown for sufficient S/N/sub 0/ and angular separation between the target and the interference sources.<<ETX>>

  • Adaptive Techniques for MIMO Radar

    By transmitting independent waveforms via different antennas, the echoes due to targets at different locations are linearly independent of each other, which allows the direct application of many adaptive techniques to achieve high resolution and excellent interference rejection capability. In the absence of array calibration errors, we discuss the application of several adaptive algorithms including Capon, APES and CAPES. When array errors are present, we apply the robust Capon beamformer (RCB) and doubly constrained robust Capon beamformer (DCRCB) approaches to the MIMO radar system to achieve accurate parameter estimation and superior interference and jamming suppression performance

  • Limits imposed by tissue on SVD-Wigner filtering to obtain the intrinsic frequency variation of ultrasonic echo waveforms

    The attenuation slope with frequency from the frequency decrease along the ultrasonic echo signal is evaluated in tissue. When the local frequency from the reflected waveform is evaluated, many data segments yield unreliable values because of interference between overlapping echo pulses. The authors advance an analysis based on the singular-value decomposition (SVD) of the Wigner distribution of the signal, which provides a criterion to filter out data segments corrupted by interference. When applied to clinical data, this SVD-Wigner filtering process reduces the scatter in the local frequency estimate sufficiently to produce a reliable estimate of the frequency slope along the signal with about one third of the data needed by conventional short-time Fourier techniques. The improvement is not larger because these clinical data were taken on a scanner with a large sample volume, so that most data segments are perturbed by interference artifacts. Simulations show that in a more tightly focused system, with fewer scatterers contributing to the echoes, the reduction in required data can be appreciable.<<ETX>>

  • 10B-1 Strain Imaging of Arterial Wall with Translational Motion Compensation and Error Correction

    To assess elastic properties, correlation techniques are widely used to measure the displacement and strain of the arterial wall caused by the heartbeat. However, the displacements estimated by the phase-sensitive correlation methods are biased when the frequency used for the displacement estimation is different from the center frequency of RF echo. One of reasons for the frequency variation is the interference of echoes. In the case of the arterial wall, the displacement due to radial translation is larger than that contributing to strain by a factor of 10 and, thus, the error resulting from the translational motion due to the mismatch between the frequency used for displacement estimation and the actual center frequency is not negligible compared with the minute displacement contributing to strain. In this study, a method is proposed in which the radial translation is removed prior to the calculation of complex correlation between echoes in two different frames to estimate the phase change between the echoes. The radial translation is removed by tracking the echo from the luminal interface of the wall because it is dominant compared with echoes from scatterers in the wall and is less affected by the interference. Using this procedure, the significant error resulting from the large translation can be greatly suppressed. After the removal of translation, an error correcting function based on complex correlation is introduced to further reduce the error due to the frequency mismatch. Accuracy improvement by the proposed method was validated using phantoms. As shown in the figure, the error in strain estimated by the proposed method was 12.0% from the theoretical strain profile, significantly smaller than that (23.7%) by the conventional method. Furthermore, in the in vitro experiments using extracted femoral arteries, the arterial wall containing calcined tissue showed very small strain in comparison with that almost homogeneously composed of fibrous tissue (mixture of smooth muscle and collagen). The means and the standard deviations of distensibility (calculated from strain and internal pressure) of fibrous and calcined tissues obtained for 7 sections of 5 femoral arteries were 2.42plusmn2.1 and 0.35plusmn0.50 MPa<sup>-1</sup>, respectively.

  • Robust semi-transparent volume rendering of abdominal 3D ultrasound data

    A new method for surface- and depth-shaded volume rendering of medical ultrasound data is presented. Robust semi-transparent rendering is obtained using a special opacity function which includes both echo intensities and echo gradients. Interactive cutting of the 3D scene with randomly oriented 2D slices was essential for the clinical use of the system. A device for mechanical tilting of a standard 2D probe was used to record the ultrasound data. The new method has been successfully used in examining both structures with distinct tissue transitions such as the gastric antrum wall and liver cysts, and more fuzzy structures such as hyper- and hypo-echoic tumors in the liver and pancreas

  • A new method for anti-noise FM interference

    Noise frequency modulated (NFM) interference causes a disaster to almost all types of radar systems. The echo signal and the interference are overlapped because of the strong energy of the NFM interference, and in the radar receiver system nothing could be detected except the interference. Up to now no good method against NFM has been declared, conventional methods are based on the passive radar to track the interference source. Here a new anti-noise FM method is proposed to suppress the NFM interference, the method multiply the echo signal two times by different reference signals, and results show that the method can eradicate NFM effectively which is useful for detecting and tracking the target. Whatpsilas more, in the presence of several interferences from different directions, the passive Radar can not track the interference source but the method supposed here can work well.

  • Time-of-flight estimation using extended matched filtering

    The problem considered is the estimation of the ToF (time-of-flight) of an acoustic tone burst in a reflective environment. Secondary echoes cause a complex interference pattern. Only the ToF of the first echo is of interest. Conventional matched filtering (MF) cannot cope with overlapping echoes. An explicit model for overlapping echoes leads to a generalized MF consisting of a parallel bank of filters rather than just a single filter. The new method is evaluated with a dataset of 150 records of observed waveforms using 3-fold cross validation.
