Single-channel radar main lobe interference separation method and device and computer equipment

The invention relates to a single-channel radar main lobe interference separation method and device and computer equipment. The method comprises the following steps: receiving an observation signal through a single-channel radar, and discretizing the observation signal in a first preset period to obtain a plurality of discrete signals; performing virtual multi-channel sampling and rearrangement on the obtained multiple discrete signals to obtain a virtual multi-channel signal matrix, and performing pulse compression on each virtual channel signal in the virtual multi-channel signal matrix to obtain a virtual multi-channel pulse compression signal; and obtaining the number of signal sources according to the virtual multi-channel pulse compression signal, and performing main lobe interference separation on the virtual multi-channel pulse compression signal by taking the number of the signal sources as prior information and adopting a blind source separation algorithm. By adopting the method, the target signal c
