  • Position finding based on multiple doppler sensors

    Nowadays knowledge about the position of persons indoors is relevant for a huge number of problems. An increasing number of modern applications and services is based on information referring to the users actual position and in some cases also on its velocity. In addition to these location based services also safety and security relevant tasks require these informations, e.g. critical infrastructure (CI) or small area surveillance. In outdoor scenarios the GPS-System is often used, but not all of the already existing wireless infrastructure is capable of providing the position information needed, especially in indoor environments. For this case several approaches can be found in the literature. Most of them adopt the GPS-principle thus needing additional infrastructure and objects actively participating in the position finding task. We will present a system that is based on doppler measurement and only analyses a relative distance information between the object to be detected and four very basic sensors. Therefore no cooperation of the object is needed which is very important for the mentioned security relevant applications. The design of a 4-channel demonstration system will be shown and practical results obtained with this demonstration system will be given.

  • Doppler measurement and compensation in mobile satellite communications systems

    The frequency errors dominated by the dynamic Doppler is analyzed for mobile satellite communication systems employing fast-moving satellites. Methods are proposed and analyzed for the basestations to measure and compensate the dynamic Doppler of large range. It is shown that the proposed methods give the minimum uncertainty of the dynamic Doppler for the modem to handle. Therefore, these methods are optimal for frequency synchronization and Doppler measurement in mobile satellite communications systems.

  • A geolocation method using ToA and FoA measurements

    In this paper, we describe a geolocation method using time of arrival (ToA) and frequency of arrival (FoA) measurements. The proposed method has been developed in particular for Global Navigation Satellite Systems (GNSS) like the American Global Positioning System (GPS) and the forthcoming European navigation system GALILEO. Most commercial GNSS receivers calculate their position based on ToA measurements. By exploiting the additional information of the FOA measurements we want to provide more robust position estimates under severe environmental conditions. Whereas the ToA method requires at least four measurements, with the described approach it is possible to provide a position estimate using less than four satellites in view. For the navigation algorithm we applied a least square (LS) approach.

  • A comparison of IIR initialization techniques for improved color Doppler wall filter performance

    The performance of exponential initialization, a novel infinite impulse response (IIR) filter initialization technique, was compared with that of three existing initialization techniques, zero, step, and projection in the context of color Doppler wall filtering. A simulation which uses a statistical estimation approach, was developed to evaluate the performance of each of the initialized IIR filters in terms of their effect on frequency estimation and tissue echo suppression. The results show that the wall filters examined here introduce a degree of bias into Doppler frequency estimation which depends on the IIR initialization technique, the filter cutoff frequency, the number of Doppler samples in the sample volume, and the input signal statistics. In addition, the realized frequency response is compromised relative to the desired steady state IIR response. Exponential initialization is shown to exhibit the least frequency estimate bias

  • Maximum likelihood and maximum a posteriori estimation of Gaussian spectra. Application to attenuation measurements and color Doppler velocimetry

    We address the problem of tracking slowly varying mean frequency and spectral width from a series of data vectors y<sub>p</sub> (p=1, 2, ... P). When the y<sub>p</sub> are small-sized, usual methods (periodogram, correlation lags...) suffer from strong variability. Moreover, the discrete nature of observed signals results in ambiguity in spectral domain. First in a Gaussian setting both for the shape of the spectra and for the statistics of observed signals, a maximum likelihood (ML) technique is provided for spectral moments estimation. Second, we propose a maximum a posteriori (MAP) method in order to account also for the slowly varying character of the spectral moments. Noticeable improvement are obtained with respect to usual methods: strong variance reduction in the field of ultrasound attenuation measurement (AM), and correct estimation beyond the Shannon limit in the field of color flow mapping (CFM)

  • Second harmonic imaging and harmonic Doppler measurements with Albunex

    The application of ultrasound contrast agents, such as Albunex, sometimes reduces the image contrast between blood and the surrounding tissues. This paper proposes experimental procedures that could alleviate this problem considerably by using harmonic signals generated by nonlinear backscattering of the microbubbles. In addition, its application on Doppler can minimize the clutter problem resulted from the motion of surrounding tissues and thus enables the detection of slow blood flow, in both power Doppler and color Doppler imaging modes. Results show that: (1) second harmonic signal produced by Albunex is significant and harmonic images that filter out backscattered echoes from solid tissues, but not those from Albunex, can be obtained; (2) when these microbubbles are compared to polystyrene microsphere suspensions which possess exclusively linear behavior, Doppler power at second and subharmonic frequencies could only be detected from Albunex

  • AUV mission preparation as a multi-criteria optimization problem using statistical performance prediction

    This paper addresses the problem of designing the key parameters defining a mission of an AUV. The novelty of our approach consists: (i) in the formulation of mission design as a multi-criteria problem and use of an appropriate optimization tool, and (ii) on the use of statistically based performance prediction tools.

  • The perveance function (particle accelerators)

    A method of analyzing the divergence characteristics of particle beams that utilize a Pierce geometry accelerator is described. The technique combines measurements of gradient grid current and arc current to develop an analytic expression, (perveance function), that could prove beneficial to beam operations. Unlike thermocouple or Doppler measurements of beam divergence, which only indicate the magnitude of the beam angle, the perveance function exhibits bipolar linearity with arc current changes. Additionally, the value of the arc current at which the perveance function equals zero is the operating point for minimum beam divergence. As a result, a single measurement with the perveance function can indicate whether the beam is overfocused or underfocused, and also determine the change in the magnitude and direction of the operating point to achieve optimum focus. This method is superior to present procedures, which tune the source by hunting for the minimum divergence. The perveance function is a relatively simple relationship that can be easily realized in hardware electronics or computer software.<<ETX>>

  • A catheter mounted Doppler system for the continuous measurement of cardiac output

    Since the introduction of a flow-directed pulmonary artery catheter in 1970, the most extensively used technique for the invasive measurement of cardiac output (CO) has involved the measurement of the thermal dilution of chilled saline injected into the right heart. The authors report the successful combination of the ultrasound Doppler measurement of pulmonary artery velocity profile with thermal-dilution CO measurements to permit the tracking of changes in heart output and thus the continuous monitoring of CO.<<ETX>>
