Detection of the Stochastic Objects in Multiposition SAR

Abstract

Proposed detection method in multiposition SAR is a high-stable, allows to detect objects with high probability of true detection along with low probability of the false alarm in comparison with monostatic/bistatic SAR.Significant advantages of the multiposition SAR are possibility to detect objects hidden for some bistatic pairs; possibility to detect targets even if their backscattering diagram is "almost zero" for some receivers (stealth objects as well); possibility of detection and identification of objects, width of which is closer/smaller than resolution. Optimal and quasioptimal detection algorithms were derived for two kinds of the objects- given by distribution of the complex scattering coefficient and objects given by distribution of the statistical characteristics of the object complex scattering coefficient.
