Multi-target detection using noise-like signals

Both the generalization to space-time adaptive processing (STAP) and to an arbitrary number of targets, of a multiple beamforming technique and its adaptation to noise-like signals are presented in this paper. A hybridization of both the joint domain localized (JDL) and the direct data domain (D³) STAP methods is used to prove the feasibility of multi-target detection in the presence of either homogeneous or nonhomogeneous interferences. This technique is applied to digital video broadcasting-terrestrial (DVB-T) signals in order to prove the feasibility of a passive DVB-T-based multi-target bistatic radar.
