摘要
为了对红外/微波共口径目标模拟器的电磁特性进行有效的仿真分析,采用全波数值算法矩量法(MOM)、多层快速多极子(MLFMM)算法和高频近似物理光学法(PO)相结合的混合电磁算法对所设计的红外/微波共口径目标模拟器电场的幅度和相位进行了计算,并对该模拟器应用于测试比幅单脉冲接收机特性进行了仿真计算,仿真结果表明:共口径目标模拟器能够很好的对红外/微波复合比幅单脉冲接收机红外与微波测角指向的一致性进行评估。
The analysis of electromagnetic characteristic of infrared/microwave coaperture target simulator is very important. The hybrid electromagnetic methods including Moment Method, Multi-level Fast Multipole Method and Physical Optics Method are used in this paper for computation of amplitude and phase of the designed co-aperture target simulator. The monopulse case using this target simulator is also analyzed. Simulation results show that the electromagnetic characteristic of the infrared/microwave coaperture target simulator designed in this paper can be used for evaluation of consistency of angle direction.
