Abstract
A radar system including an AESA illuminates a target with a first pulse for a desired beam pointing angle (azimuth and elevation). The AESA then illuminates the target with a second pulse for the desired pointing angle, the second pulse defining a radiation pattern with a main beam in phase with the first pulse, but side lobes that are out of phase. The radar system receives return signals and combines the return signals to null the side lobes by the principle of superposition. The radar processing unit is time synced such that the pulse-pair is interpreted as a single ultra-low level side lobe return radiation pattern.
