天线性能对被动毫米波探测器信噪比的影响

Effect of Antenna Property on SNR of a Passive Millimeter Wave Seeker

本文分析了天线增益和电压反射系数幅值对被动毫米波探测器信噪比的影响，并用边馈微带平面阵列天线做实验测试，实验结果与理论分析相吻合。

The effect of antenna gain and voltage reflectivity on the SNR of a passive millimeer wave seeker is analyzed. Simulated test results of a seeker SNR with microsrip planar array antennas are given and they are in good agreement with the analytical results.
