激光相干阵列成象雷达系统光束整形的研究

Research on the Beam Shaping of the Laser Coherent Array Imaging Radar System

激光相干阵列成象雷达系统中本振光波前与信号光波前匹配与否直接影响系统的灵敏度和分辨力。采用共轭光栅合成技术对相干成象本振光束作整形处理，以适应探测器阵列及合成输出满足最佳信噪比条件。

The matching of the local light wavefront and signal light wavefront in the laser coherent array imaging radar system will directly affect the sensitivity and resolution of the system.The shaping processing for the coherent imaging local beam is carried out by means of the conjugate grating synthetic technique,thus the detector array can be suited and the synthetic output can meet the optimal signal noise ratio conditions.
