Antenna pattern synthesizing apparatus and method
First Claim
1. An antenna pattern synthesizing apparatus, comprising:
- a designer configured to design a mask template based on a performance of a synthetic aperture radar (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 quantum-behaved particle swarm optimization (QPSO), and generate the first antenna pattern in the designed mask template based on the calculated signal amplitude and the calculated signal phase.
