Abstract
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.
