A method is presented for calculating the performance margins of the optimum likelihood ratio detector by using Monte Carlo Simulation. The method is applicable to communication, sonar and optical signal detection for determining the optimum marginal performance obtainable in some kind of clutter. This marginal performance can identify the deviation of the various detectors from the optimum likelihood ratio detector.

本文提出了用Monte Carlo模拟计算理想似然比检测器检测性能的数值方法。该方法比以前有人提出的方法简单、精确得多。它也可应用于通讯、声纳、光学等信号检测领域中,以求得把似然比作为最佳检测准则时在某种杂波下可能得出的最佳边界性能。利用这一性能边界,就可鉴别各种实际检测器相对最佳检测边界性能的偏离程度。
