METHOD FOR SYNTHESIZING AN ANTENNA RADIATION PATTERN OF A SYNTHETIC APERTURE RADAR USING A PSO METHOD AND A REPETITIVE OPTIMIZATION METHOD

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).;COPYRIGHT KIPO 2011
