摘要：
To efficiently compute and reduce radar cross section (RCS) of active phased array antenna, and to balance the performance of the radiation and scattering, a novel coupled structural-electromagnetic model of the array RCS factor of active phased array antenna is developed based on the phase errors of the array elements caused by antenna structural distortion and installation. According to the coupled model, the particle swarm optimization method is used to obtain the optimal installation height of all the array elements for the better radiation and scattering performances of active phased array antenna. The simulation results prove that the developed model and the integrated optimization method can effectively reduce the RCS of active phased array antenna with good radiation performances, which demonstrates an important application value in engineering. ©, 2015, Chinese Institute of Electronics.
