Abstract
Provided is an antenna pattern synthesizing apparatus that synthesizes an antenna pattern by applying quantum-behaved particle swarm optimization (QPSO) algorithm of a satellite synthetic aperture radar (SAR), the antenna pattern synthesizing apparatus including a designer configured to design a mask template based on a performance of an SAR system including an antenna array in which a plurality of antennas are arranged in a multidimensional structure, and a generator configured to calculate a signal amplitude and a signal phase for the antenna array to generate a first antenna pattern using QPSO, and generate the first antenna pattern in the designed mask template based on the calculated signal amplitude and the calculated signal phase.
