Abstract
This paper describes the implementation case of SLB (Side Lobe Blanking) function in the AESA radar antenna. With the limitation of size and weight request in an airborne radar, we utilized a part of AESA antenna module as the SLB antenna. The measured near-field antenna pattern shows the validity of main channel and SLB channel pattern. Noise power was compensated according to the amplitude tapering mode. The implemented SLB function is verified using the AESA radar demonstrator as part of the radar development program. The ground roof-lab test shows the implemented SLB function working under the unwanted signal which intentionally inserted to side lobe position. The cargo aircraft flight test validates the SLB function in the real ground clutter environment.
