S. Elayaperumal, G. N. Rathna · 2019
In phased array radar with element level digital beamforming, Cognitive Adaptive Array Processing (CAAP) technique allows adaptive jammer cancellation with very very less computational load compared to the Sample Matrix Inversion (SMI) technique. Previously published paper on this technique showed the performance analysis of CAAP with SMI for a linear array with element level digital beamforming. In this paper firstly, a mathematical model is developed to simulate the jammer and target signal with various scenarios for a planar array. Secondly performance analysis of CAAP with SMI is done for planar array with the sizes corresponding to the practical use.
