When there are radiation signals with large bandwidth and rapid frequency hopping in space, traditional reconnaissance receivers cannot achieve complete reception and accurate identification. Aiming at the above problem, a broadband refined reconnaissance processing method is proposed. By this method, the broadband real-time data acquisition and refined time-frequency analysis are realized. Also the characteristic parameters of multiple radiation source signals are accurately classified. In addition, the complete radiation source situation information is generated and effective enemy behavior is predicted. The experimental results show that the method can realize the full probability reception and accurate analytical measurement of broadband high-speed frequency hopping signals, which has engineering realization value.
