We discuss the space-time adaptive processing (STAP) for non-side-looking airborne radar (SLAR). The clutter specific property of the airborne radar when the phased array antenna is placed on the aircraft in an arbitrary direction is discussed. Then the STAP of the non-SLAR is studied. A scheme has been proposed, which is processed by way of adaptive space-time processing combined with using multiple pulse repetition frequencies (PRFs). We analyze the system performance by using an approach, which is effective to the SLAR and can be realized in real-time processing. We also study the selection of the PRFs. Computer simulation results show this scheme is feasible.
