Electromagnetic situation awareness evaluation system for electronic countermeasure equipment trial training

The invention relates to an electromagnetic situation awareness evaluation system for electronic countermeasure equipment trial training. An antenna feed subsystem receives a space radiation signal in all directions; the radio frequency subsystem performs primary frequency conversion processing on the radiation source signal to output a broadband radio frequency signal, and performs secondary frequency conversion processing to output an intermediate frequency signal; the intermediate frequency signal acquisition subsystem acquires and stores baseband data; the signal monitoring and recording subsystem is used for acquiring and analyzing time domain and frequency domain data of the broadband radio frequency signal and evaluating an electromagnetic situation; the full-band calibration subsystem is used for calibrating the system function and performance; and the data post-event analysis processing subsystem completes high-speed transfer and offline analysis and evaluation processing of big data.
