%X In this paper, an innovative airborne forward-looking SAR system using antenna array is studied, and a new three-dimensional imaging algorithm is proposed for airborne forward-looking SAR based on the image geometry and the characteristic of echo signal. A single SAR image was obtained with chirp scaling algorithm until all the receiving antennas have received echoes once. When plane flies along the track continuously, a sequence of two-dimensional SAR images in front of the flight path can be obtained. Then the three-dimensional image of forward-looking SAR can be obtained by focusing one section at an azimuth position one time with Range-Doppler algorithm until all the sections have been processed. 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 confirm the validity of the proposed algorithm.
