Signal processing considerations for passive radar with a single receiver

Processing of passive radar signals is hindered by the presence of clutter and sensor noise in the reference signal, and by strong direct and zero-Doppler clutter returns in the surveillance signal. Previous research has addressed methods of removing or mitigating unwanted components in either signal. However what is considered as interference in one signal may be considered as information in the other. In this study we investigate under what conditions both surveillance and reference information may be extracted from a single signal, thus enabling passive radar processing with a single receiver.
