Synthesis of optimized patterns from thinned arrays

Abstract

Difference patterns find their applications in radar tracking. There rises a need to generate such patterns with minimum sidelobes to reduce clutter and interference in accurate target tracking. A popular technique used for low sidelobe pattern generation is thinning. It reduces the number of elements active in the overall system. In addition to reducing sidelobes, it also reduces cost and weight. In the current presentation, low sidelobe difference patterns are generated from thinned linear assortments. Differential Algorithm is made use of for the pattern generation. Optimized patterns are portrayed for different number of elements. The results computed show good sidelobe level reduction without enhancing beamwidth between first nulls.
