摘要 该文针对微弱回波信号的检测,在二次门限检测过程中引入约束判决。就约束判决对总虚警概率的改善作用及对总检测概率的影响进行了定量分析,建立了基于约束判决的二次门限检测总虚警概率和总检测概率的数学模型,并对模型的有效性进行了仿真验证。仿真结果表明,将约束判决引入二次门限检测可以保证在总检测概率和总虚警概率满足预定指标的条件下降低对信噪比的要求。 Double threshold detection based on constraint judgment is proposed for weak signal detection. The improvement effect on Probability of False Alarm （PFA） and influence on Probability of Detection （PD） are quantitatively analyzed with constraint judgment. The mathematical models of total PFA and PD of double threshold detection based on constraint judgment are built, and the validity of the mathematical models is verified by simulation tests. The simulation results show that the signal-to-noise ratio under scheduled PFA and PD can be decreased by introducing constraint judgment to double threshold detection.
