To solve the problem that the forward direction of radar does not have enough Doppler bandwidth thus it is difficult to use the Synthetic Aperture Radar (SAR) imaging technologydeep researches have been carried out on the radar forward imaging technology from multiple aspectsand have been applied in missile precision striketerrain recognitiontarget positioning and aircraft autonomous landing.This paper comprehensively introduces the history of the researches on forward-looking imaging technologyand make classification to the technology systematically according to imaging principleradar model and detection signals.The basic principles and characteristics of the imaging technology based on convolution inversion single pulse imaging technologymicrowave correlation technologyarray radar imaging and bistatic forward-looking imaging are mainly described.The research status and development trend of various forward-looking imaging technologies are summarized.
