Abstract When the target and the active jamming with different space angles exit simultaneously in the radar beam main lobe, the target echoes are overwhelmed by the interference with certain bandwidth in time domain and frequency domain, so the Monopulse radar cannot effectively detect the target, and the output of angle measurement system is the wavefront of the distortion after the superposition of the jamming signal and the echo signal. In view of target detection of radar under jamming conditions, this paper studies the signal extraction and processing algorithm of Monopulse radar double-delta channel, and proposes the angle measurement technology based on double-delta channel under the main lobe interferenceso as to improve the adaptability of radar in complex electromagnetic environment.
