| Abstract: | In this paper,an innovative air-borne forward-looking SAR system using antenna array is studied,and three-dimensional imaging principle is analyzed.A three-dimensional imaging process is proposed for air-borne forward-looking SAR based on the image geometry and the characteristic of echo signal,and the resolutions in three dimensions are derived.Raw data of forward-looking SAR in X-band is simulated and three-dimensional image is achieved.The imaging result is analyzed,and simulation results show that the f... |
