中文摘要	提出了一种合成孔径激光成像雷达(SAIL)的二维匹配滤波成像算法,对利用单频本振激光与线性调频信号光外差接收得到的SAIL目标回波信号同时在距离向、方位向进行相位二次项匹配滤波以实现目标成像。给出了单频本振信号外差接收情况下的单一分辨单元的二维数据收集方程,并对SAIL二维匹配滤波成像算法进行了数学描述,具体分析了矩形和圆形天线孔径下的成像分辨率,给出了此算法对模拟SAIL回波信号的成像处理结果。
英文摘要	A two-dimensional (2D) matched filtering imaging algorithm for synthetic aperture imaging ladar (SAIL) is proposed. This algorithm simultaneously performs quadratic phase matched filtering in range and azimuth direction for the data obtained through heterodyne detection with single frequency local oscillator and linear frequency modulation signal light to achieve target image. The SAIL 2D data-collection equation of point target through heterodyne detection with single frequency local oscillator is presented. Imaging process of the algorithm is mathematically analyzed. Imaging resolutions of the algorithm for the SAIL with rectangular and circular apertures are described specificly. Imaging result of simulated SAIL echo data is presented.
