Microwave Staring Imaging Scheme And Imaging Algorithm Based On One Dimensional Wavefront Modulation

Synthetic Aperture Radar(SAR)is currently the main forms of technology in the field of remote sensing imaging,having all day,allweather imaging observation capabilities,.But as an essential means of virtual aperture synthesis,microwave imaging synthetic aperture radar technology under the system in relative motion between the radiating element and the target can be accurately measured as the basic conditions,such conditions make synthetic aperture radar motion must go through certain cycles to cover the entire scene detection,scene detection area with the revisiting period proportional.This paper proposes a one-dimensional wave front modulator based on microwave staring imaging system,the establishment of this system based on the existing radar system,the reference optical imaging theory,at a distance of up classic pulse compression technology to achieve high range resolution,The associated reference optics imaging thought up in azimuth by unrelated one-dimensional wave front modulation technique coupled target scene scattering process information and use associated with scattering information extraction,to achieve high-resolution imaging.In addition,the paper staring imaging algorithm simulation,analysis and noise analysis aspects of performance and image quality aspects were studied on the structure of the wavefront really tested the receiving antenna structure wavefront.Finally,we propose a synthetic aperture imaging information processing technology compatible gaze,staring imaging technology makes use of such systems can on the one hand,there is slow relative motion between the scene and,relying on low-resolution synthetic aperture imaging system,and the other aspects of imaging techniques can be used to further enhance the image staring at synthetic aperture system obtained.
