Particle Swarm Optimization Algorithm for the Design of Phase Distribution to reduce Quantization Lobes

Author Name : B. Kiran Kumar

ABSTRACT

In phased arrays, quantization lobes appear most often even without phase. However, it is possible to reduce them by optimal design of phase distribution. Keeping phase distribution fact in view, Particle Swarm Optimization Algorithm is used to design suitable phase distribution which could reduce quantization lobes. A linear array is considered in the present work. The optimized phase obtained with Particle Swarm Optimization algorithm, resulted in the reduction of unwanted lobes by 9–10 dB. These results are useful for radar applications. The patterns are numerically computed for large and small array and are presented in sin θ domain.

Keywords: Quantization lobes, Radiation pattern, Particle Swarm Optimization Algorithm.
