Integration Multi-Objective Optimization Method of Airborne Radome System

Abstract

To improve the characteristics of boresight error (BSE) and power transmission coefficient in a phased array antenna-radome system, an integration optimization method, adjusting radome structure and antenna excitation successively, is studied. A multi-objective fitness function is designed for the particle swarm optimization (PSO), which obtain the performance parameters by Aperture Integration-Surface Integration (AI-SI) method. The results obtained are compared with those achieved by pure radome optimization, showing the effectiveness of the proposed method.
