High-speed motion platform radar vector non-uniform modulation angle super-resolution method

The invention discloses a high-speed motion platform radar vector non-uniform modulation angle super-resolution method, which comprises the following steps of: firstly, acquiring echo data and preprocessing along a distance dimension to realize echo distance dimension high-resolution imaging, and then constructing a non-uniform antenna pattern matrix and a Doppler phase matrix according to a relative position relation between a platform and a target; and finally, a sparse constraint optimization problem is solved by adopting a non-parameter iteration reweighting norm, a super-resolution result is output, and reconstruction of the sparse target of the high-speed motion platform is realized. According to the method, in echo modeling, a non-uniform antenna pattern matrix and a Doppler phase matrix are constructed, the adaptability of the angle super-resolution method to a high-speed motion platform is improved, and the problem of large imaging result error of an existing convolution approximation model under the
