Multichannel Along-Track Interferometric SAR Systems: Moving Targets Detection and Velocity Estimation
Along-track interferometric synthetic aperture radar (AT-InSAR) systems are used to estimate the radial velocity of targets moving on the ground, starting from the interferometric phases, obtained by the combinations of two complex SAR images acquired by two antennas spatially separated along the platform moving direction. Since the radial velocity estimation obtained from a single-phase interf...
متن کاملFixed-point FPGA Implementation of a Kalman Filter for Range and Velocity Estimation of Moving Targets
Tracking filters are extensively used within object tracking systems in order to provide consecutive smooth estimations of position and velocity of the object with minimum error. Namely, Kalman filter and its numerous variants are widely known as simple yet effective linear tracking filters in many diverse applications. In this paper, an effective method is proposed for designing and implementa...
متن کاملClutter Effects on Ground Moving Target Velocity Estimation with SAR Along-Track Interferometry
Abstract—The SAR interferogram, defined as the product of the first channel and the complex conjugate of the second, is one way of comparing two SAR channels. When the two subapertures are aligned along the flight path, targets with nonzero radial velocities can be detected by exploiting the phase information of the interferogram. This paper examines the effect of clutter interference on the in...
متن کاملError Analysis of Velocity Estimation via Bistatic Along Track InSAR
Bistatic SAR uses separated transmitted and receiver flying on different platforms. Such a spatial separation has several operational advantages in military applications the vulnerability of the system is reduced, because the transmitter can be positioned far away, while the passive receiver is difficult to locate. The bistatic along track interferometric SAR (AT−InSAR) model is one kind of bis...
متن کاملMoving Target Detection by Along-Track Interferometry
In this paper we consider the detection of a moving point target using Along-Track (AT) InSAR systems. We consider two cases: conventionally and one bit coded raw data. The performance of the system is evaluated by comparing the probabilities of false alarm and detection.
