The paper concerns the estimation of Target Motion Parameters (TMP) viz. Range, Bearing, Course and speed of a moving target, from noisy corrupted data. A sensor is used to obtain the Frequency and Bearing parameters of the target in this type of environment. The estimate of all TMPs is obtained by processing of these parameters data. Doppler Bearing passive target tracking is the determination...

The railway occupies a fairly important position in transportation due to its high speed and strong transportation capability. As a consequence, it is a key issue to guarantee continuous running and transportation safety of trains. Meanwhile, time consumption of the diagnosis procedure is of extreme importance for the detecting system. However, most of the current adopted techniques in the ways...

This paper introduces a novel method for bearing estimation based on a rotating antenna generating a Doppler shifted RF signal. The small frequency change can be measured even on low cost resource constrained nodes using a radio interferometric technique introduced previously. Measuring the Doppler shift at two known locations provides a bearing estimate to the rotating node. An alternative app...

The GPS modernization program deploys new generations of satellites designated Block IIR-M, Block IIF and Block III-A, equipped to transmit multiple civil signals. The coexistence of multiple civilian signals in a GPS receiver has been a focus in recent research activities. In the literature to date, correlator outputs of individual channels are combined in ways either to increase the power ava...

In ultra-tight GPS/INS integration, a Doppler signal derived from INS navigation data and GPS satellite ephemeris is integrated with the receiver tracking loops to remove the dynamics from the GPS signal. It is well known that this integration architecture provides several advantages such as improved S/N ratio, better ‘immunity’ to interference and jamming signals, lower order tracking loops ev...

BACKGROUND This study evaluated 3 new automated methods, based on a combination of speckle tracking and tissue Doppler, for the analysis of strain rate (SR) and strain. Feasibility and values for peak systolic strain rate (SR s ) and end-systolic strain (S es ) were assessed. METHODS Thirty patients with myocardial infarction and 30 normal subjects were examined. Customized software with auto...

A novel approach of the integrated security and dynamic Position Location and Tracking (PL&T) for malicious node maintaining two friendly nodes is proposed. Location based hash security scheme is deployed for detection of friendly and malicious nodes by encrypting hash functions using private location assets to increase the security level. In addition, PL&T is deployed forming the robust tracki...

Ronald Mahler’s Probability Hypothesis Density (PHD) provides a promising framework for the passive coherent location of targets observed via multiple bistatic radar measurements. We apply a particle filter implementation of the Bayesian PHD filter to target tracking using both range and Doppler measurements from a simple non-directional receiver that exploits non-coöperative FM radio transmitt...
