Abstract
A signal processing method performs operations of coherent processing making it possible notably to purge the useful signal of the spurious signals (in particular the reference signal and its multiple reflections), to regenerate the transmission signal and to perform a coherent integration of the signal received by computing the cross-ambiguity between the signal received and the regenerated transmission signal. It also performs operations of non-coherent processing making it possible in particular to carry out extraction and Doppler distance purification operations making it possible to form blips and to eliminate the spurious blips present among the blips formed. The method applies notably to passive radars operating on non-cooperating opportunity transmissions, such as FM transmissions intended for the public.
