METHOD FOR COMPOSING A RADIATION PATTERN OF ANTENNAS IN A SYNTHETIC APERTURE RADAR SYSTEM

摘要

PURPOSE: A method for synthesizing an antenna radiation pattern of a synthetic aperture radar is provided to optimize the performance of the image radar of a phase arrangement synthetic aperture radar by synthesizing a mask template with an antenna radiation pattern. CONSTITUTION: An antenna mask template suitable for a parameter of a radar system and a geometric configuration of a radar with a plurality of antenna radiation devices of a two dimensional structure are designed(S210). The optimal distribution of the phase and amplitude of a phase arrangement antenna is calculated by using PSO(Particle Swarm Optimization) method. An antenna radiation pattern is synthesized with an antenna mask template(S220).
