The invention discloses a single-channel staggered synthetic aperture radar imaging method based on dead zone data recovery. The method mainly solves the problem of imaging grating lobe caused by deadzone data loss in the prior art. According to the implementation scheme, a pulse repetition interval PRI sequence is an increasing sequence; a PRI sequence design formula is determined according to parameters in a target scene, and a PRI agile sequence is solved; dead zone data are recovered by using a data interpolation method; non-uniform fast Fourier transform is used to resample non-uniform sampled data after dead zone data interpolation; and finally a traditional imaging algorithm is used to image the data. According to the invention, the PRI sequence is optimized, which effectively reduces the requirement of the system duty cycle in a PRI sequence design method; grating lobe caused dead zone data loss is solved; and the method can be used for azimuth single-channel staggered synthetic aperture radar imaging to acquire a good imaging result.
