Zusammenfassung: | The invention, which belongs to the technical field of forward-looking radar imaging, in particular relates to a super-resolution imaging method of a forward-looking radar. According to the invention,an azimuth deconvolution model is constructed; and a singular value being obvious to noise amplification in an iterative process is found out from the perspective of the mathematics, so that the amplification transmission of the noise in the iterative process is suppressed. Therefore, the deconvolution has the better resolution performance in realizing radar super-resolution imaging.
