Design and Analysis of Adaptive Sidelobe Blanking Architectures

The paper starts with a brief retrace of some seminal publications of Dr. K. R. Gerlach on adaptive antennas. This legacy motivates the core of the present paper which addresses the design of SideLobe Blanking (SLB) architectures capable of providing Electronic Protection (EP) against a coherent repeater interference in the presence of continuous jamming signals. In this respect, a generalized adaptive beamforming technique which synthesizes the SLB auxiliary channel output, is introduced. Then, an optimization algorithm is developed to design the adaptive weights so that the resulting outputs fulfill SLB specific requirements. The effectiveness of the resulting architecture is assessed in terms of sidelobe pattern and continuous jamming rejection.
