Airborne radar foresight imaging method based on alternating direction multiplier method network

The invention discloses an airborne radar foresight imaging method based on an alternating direction multiplier method network, and the method comprises the steps: firstly, receiving an airborne radar echo signal through a single channel, and inputting an obtained real beam scanning result, namely complex image data, into an ADMMN for training after pulse compression and range migration; secondly, an airborne radar forward-looking imaging network based on the ADMMN is constructed, the airborne radar forward-looking imaging network comprises n levels, each level comprises three sub-layers, namely, a reconstruction layer, a nonlinear transformation layer and a multiplier updating layer, and finally a result is output by the reconstruction layer; secondly, providing a network training method based on a high-fidelity synthetic aperture radar image simulation sample-label set to complete high-precision training of the network; and finally, inputting an azimuth low-resolution simulation image and a radar actual mea
