Signal processing for airborne passive radar

The airborne passive radar signal processing for moving target detections can be segregated into a two-step interference cancellation process where the random range sidelobes couplings of the direct path and of the strong clutter are to be first suppressed. Further cancellation of the residual sidelobes couplings and on the spatial-Doppler dependent clutter is then achieved using reduced-dimension space-time adaptive processing. Ground-based moving passive radar experimental trials are conducted which validated the proposed signal processing schemes.
