摘　　要：分析了开展“软性”空间对抗的技术途径，得出必须实现精确对准目标的有效作用面的结论，提出了一种对非合作目标进行成像、解算视轴与有效作用面夹角、然后对本体进行轨道机动开展精确对准的策略。该方法的主要过程是在对抗系统完成捕获、瞄准、跟踪后，由目标投影成像结果，展开作用面的图像分割与识别。以侦察卫星的圆筒形目标为例，分别提出了在目标大、小偏角阶段获得轨道机动控制偏差的计算方法。实验证明该方法是在“软性”空间对抗中进行自主寻的的有效途径。A realization process of developing ＂soft＂ space countermeasures technology is put forward and the necessity to aim at effective working spatial face accurately is analyzed. A method for imaging non cooperative target is advanced, which can calculate the included angle between line of sight （LOS） and the working face,and aim at the entity automatically and accurately in the orbit. The method could divide and identify the working surface based on the projective images of targets after acquiring, pointing and tracking （APT）. Taking a columned working target in the reconnaissance satellite for example,it could calculate the deviation of the orbit maneuver control with large or small angle of declination between the detective satellite axis and objective axis. It is an effective method for automatic target hunting in ＂soft＂ space countermeasures.
