Synthetic aperture radar anti-frequency shift interference method based on waveform and non-matched filter joint design

The invention discloses a synthetic aperture radar frequency shift interference resisting method based on waveform design and unmatched filter joint design. The method comprises the following steps: acquiring frequency shift interference frequency shift amount prior information; establishing a pulse compression optimization target function by taking a synthetic aperture radar waveform and a cross-correlation integral side lobe and main lobe peak value of a non-matched filter as target functions; establishing a frequency-shift interference suppression objective function according to the weighted integral level of the non-matched output of the frequency-shift interference signal; establishing an anti-frequency shift interference imaging joint design objective function, and establishing a waveform constant modulus and non-matched filter energy constraint joint design optimization problem model; decomposing a joint design problem into a waveform and non-matched filter sub-optimization problem, and solving the sub
