“…At the expense of a higher computational load, STAP has more flexibility and adaptation capability, thanks to a higher number of adaptive degrees of freedom. The use of STAP for clutter rejection in passive radar was first considered in [15] and [16]. The preliminary experimental results of STAP in a DVB-T-based mobile passive radar are presented in [17].…”

This article addresses the problem of clutter cancelation for slowly moving target detection and localization in multichannel passive radar onboard mobile platforms. A post-Doppler space-time adaptive processing (STAP) approach is exploited in the case of an angle-dependent imbalance affecting the receiving channels. While the clutter suppression capability is ensured by the adaptivity of space-time filtering, different solutions are compared, aimed at recovering the detection performance losses associated with channel calibration errors. A space-time generalized-likelihood ratio test (GLRT) scheme is considered, where the steering vector is not specified in the spatial domain, resulting in a noncoherent integration of target echoes across the receiving channels. This is compared with a fully coherent GLRT scheme where echoes from the stationary scene are exploited for the proper calibration of spatial steering vector mismatch. The first scheme proves to be a simple solution for target detection in the passive radar case, offering comparable clutter cancelation capability. The Manuscript

“…Details on the interference analysis and suppression performance have not been extensively studied where open literatures concerning this topic are rather limited. In the available open literature, a series of related papers from Warsaw University of Technology [7–11], Research Center of the French Air Force [12–14] and University College London [15, 16] present the associated work that had been conducted, suggesting that passive radar on a moving platform is indeed a feasibility concept.…”
