A NOVEL MOVING TARGET DETECTION APPROACH FOR DUAL-CHANNEL SAR SYSTEM

A Novel Moving Target Detection Approach for Dual-channel Sar System

A novel approach to moving target detection is proposed for dual-channel SAR system. This approach is on the basis of eigendecomposition of the sample covariance matrix and examines the statistic of the second eigenvalue and the Along-Track Interferometric (ATI) phase for ground moving target indication. Based on this statistic, a new Constant False Alarm Rate (CFAR) detector can be designed to...

Moving Target Detection on SAR Images

Synthetic aperture radar (SAR) is a well known technique for generating high-resolution images stationary scenes but it is not adapted to imaging moving targets as the movement of a target induces both a delocalization and a defocusing effect in a SAR image. The aim of this paper is to analyse the signatures of moving targets in SAR images and to present techniques to detect them, from one sing...

a novel navigation method for pursuing a moving target

the most current pursuit algorithms for moving targets which are presented so far in the literatureare pure pursuit and pure rendezvous navigations. recently, one of the present authors has introduced ageometric model for the pure pursuit navigation algorithm. here, in this paper, we study a new algorithm forthe pursuit navigation problem which is a combination of both of the above algorithms. ...

Techniques for ground moving target detection and velocity estimation with multi-channel Synthetic Aperture Radars (SAR)

Moving Target Motion Parameter Estimation in Two-Channel SAR-GMTI

Part 1: Two-channel SAR-GMTI systems are suboptimal for moving target motion parameter estimation. Indeed, the ATI phase estimate of a moving target across-track velocity component is biased to lower values depending on the target signal to clutter ratio and the target across-track velocity. Additional antenna diversity can introduce additional degrees of freedom th...
