A method for CLSAR 3-D imaging based on backprojection and beamforming

In this paper, a spotlight model curvilinear synthetic aperture radar system is studied and three-dimensional imaging principle of this system model is analyzed. A three-dimensional imaging processing method based on backprojection and beamforming for curvilinear synthetic aperture radar is proposed, and raw data of curvilinear synthetic aperture radar in X-band is simulated and three-dimensional image is achieved. The imaging result is analyzed, and simulation results confirm the validity of the proposed method.
