Ground-to-air intelligence radar antenna lobe parameter measurement system and method

The invention relates to the technical field of radar antenna pattern measurement, and provides a ground-to-air intelligence radar antenna lobe parameter measurement system and method. The system comprises a hardware system and a software system, and the hardware system comprises a radio frequency signal source, a test antenna, a photoelectric converter, a lobe tester, a spectrum analyzer, a router and a control computer; the radio frequency signal source is used for generating a test signal when the radar antenna receives the lobe parameter; the test antenna is used for receiving a radar emission signal or radiating a test signal to the tested radar antenna; the spectrum analyzer is used for collecting signals received by the test antenna or the tested radar antenna; and the lobe tester is used for converting and processing an azimuth signal from the radar and transmitting the azimuth signal to the control computer. The system and method can achieve quick testing of the performance indexes of the radar anten
