摘　　要：微波辐射计是一种无源微波测量装置,它本身不发射微波信号,只是被动的接收目标及环境辐射的随机噪声。微带相控阵天线采用电扫描方式,具有扫描波束灵活易控、可靠性高、装载空间较小等特点,能够解决平台装载空间和系统设计之间的矛盾,适用于机载平台。文章对应用于机载微波辐射计的双极化相控阵天线设计方法进行了研究,对相控阵天线进行仿真,并加工实物给出了测试结果。Microwave radiometer is a kind of to havepassive microwave to measure device, it doesn t shoot microwave signal and just passively receive the random noise of target and environment radiation. Due to its high efficiency and fleible beam scanning, Phase array antenna has widely used in airborne platform. The paper study of dual-polarized phased array an- tenna, Making use of the high frequency simulation software HFSS to carry on a model simulated and established. The anten- na module was tested and the measured results are present.
