在光学信息系统中,在搜索状态下信号预先处理的检波最佳运算是用统计理论方法来完成。探讨了存在关于昕观察的有一定尺度物体形状的完全凭经验的信息情况和只存在关于物体光学系统角度场中位置不确定性区间的信息情况,尤其是探测相干的和非相 In the optical information system, the optimal operation of the signal pre-processing detection in the search state is accomplished by a statistical theory method. The existence of completely empirical information about the shape of objects with a certain scale on Xin observation and the existence of only information about the uncertainty of the position in the angular field of the object optical system are discussed. In particular, the detection of coherent and non-phase
