雷达前视高分辨技术OA

Radar forward-looking high-resolution technology enables moving platforms to achieve fine angular resolution in the forward-looking area,offering significant application value and broad prospects in both military and civilian sectors,such as precision strikes,autonomous landing,and low-altitude penetration.By adopting the theory of spatiotemporal variability compatibility as a unified framework,this paper systematically elucidates the physical foundations and mathematical essence of radar forward-looking high-resolution imaging.It categorizes forward-looking high-resolution technologies into three main types:motion modulation,radiation modulation,and composite modulation,and deeply analyzes the implementation mechanisms and performance differences of various systems,including Doppler beam sharpening(DBS),bistatic forward-looking synthetic aperture radar(SAR),scanning beam sharpening(SBS),vortex electromagnetic radar(VER),and stochastic radiation radar(SRR),forming a complete forward-looking high-resolution technology system.Finally,the paper outlines future development directions for radar forward-looking high-resolution technology,aiming to provide a useful reference for researchers in the field.
