Evaluation of a Monostatic Stap Radar Range-compensation Method Applied to Selected Bistatic Configurations
نویسندگان
چکیده
The detection of slow moving targets by a moving bistatic pulsed Doppler radar system is addressed. Optimum clutter rejection is achieved using space-time adaptive processing (STAP). This requires estimating the clutter-plus-noise covariance matrix using a sequence of snapshots at successive ranges. For most monostatic and for all bistatic radar configurations, these snapshots are rangedependant. The estimator is then biased and not accurate. A compensation method originally developped for the monostatic case is applied to selected bistatic configurations and its performance assessed in these new conditions.

Principle and Evaluation of a Registration-based Range-dependence Compensation Method for Stap in Case of Arbitrary Antenna Patterns and Simulated Snapshots
We propose a new method for estimating the clutter power spectrum locus in arbitrary STAP radar configurations, i.e., both monostatic and bistatic. This locus is a surface in the 3D space of spatial frequency, Doppler frequency and range. Based on the knowledge of this locus, one can perform a range dependence compensation of the snapshots to obtain an estimate of the clutter covariance matrix....

We address the problem of detecting slow moving targets from a moving radar system using spacetime adaptive processing (STAP) techniques. Optimum interference rejection requires the estimation and the inversion of an interference-plus-noise covariance matrix. To reduce the number of samples involved in the estimation and the computational cost inherent to the inversion, many suboptimum STAP tec...
متن کاملRange ambiguity clutter suppression for bistatic STAP radar
Bistatic pulse-Doppler airborne radar has desirable properties such as the low probability of detection by other radars relative to its monostatic counterpart. However, the clutter characteristics of bistatic airborne radar are more complex than those of monostatic airborne radar. The clutter spectra not only vary severely with range, but also vary with bistatic configuration. In this article, ...
متن کاملComparison of methods for handling the range- dependence of the clutter ridge for monostatic and bistatic STAP radars
Detection of slow moving targets using a moving pulsed Doppler radar system has been a problem of great interest for quite some time [1]. One distinguishes between monostatic (MS) configurations, where the radar transmitter and receiver are colocated and bistatic (BS) configurations, where they are physically separated and have separated motions. In either case, a train of coherent pulses is tr...
متن کاملEvaluation of a Registration-Based Range- Dependence Compensation Method for a Bistatic STAP Radar Using Simulated, Random Snapshots
We address the problem of detecting slowmoving targets using space-time adaptive processing (STAP). The construction of the optimum weights at each range implies the estimation of the clutter covariance matrix. This is typically done by straight averaging of snapshots at neighboring ranges. However, in most configurations, the snapshots’ statistics are range-dependent. Straight averaging thus r...
