摘要

研究了系统中两个主体同时产生的谐波和互调积。利用互调产物，提出了一种具有12种可能输出状态的算法，对不同测试场景下的检测频谱进行分类。实验验证了双主体检测算法可以检测到两个主体而不是一个主体的存在。该技术可以在不使用定向相控阵天线的情况下实现在宽波束宽度的微带贴片天线系统中。

Intermodulation effect of detecting two subjects within antenna beamwidth of a CW Doppler radar

The harmonics and intermodulation products generated by two subjects simultaneously present in a system is studied. Utilizing the intermodulation products, an algorithm with 12 possible output states is proposed to classify the detected spectrum under different test scenarios. The two-subject detection algorithm is experimentally verified to detect the existence of two subjects versus one subject. The technique can be implemented in a microstrip patch antenna system with broad beamwidth without using directional phased-array antenna.
