A Method for Clutter Suppression for Airborne Radar Based on Power Inversion

According to the low SCR of airborne radar echo, this paper proposes a method for clutter suppression based on power inversion. This method utilizes the multiple receiver of monopulse tracking radar, and adopts the time-space processing method to process the echo. Theoretical analysis and simulation results show that this method is better than one-dimensional methods, such as AMTI. Because it is based on power inversion, the computational load of the method is greatly lighter than ASTP. So it is a simplified two-dimensional clutter suppression method which has engineering value.
