| 摘 要： | 探测概率、虚警概率是衡量红外搜索跟踪系统性能的重要指标,其大小由系统硬件水平、检测算法设计等因素决定。通过分析影响红外搜索跟踪系统探测概率、虚警概率的因素,建立了管道检测与探测概率、虚警概率关系模型,研究了序列图像检测中管道检测对系统探测概率、虚警概率的影响。通过仿真分析了实验结果,系统总检测概率与总虚警概率分别随单帧检测概率与单帧虚警概率的增加而增加,在管道长度相同的情况下,总检测概率和总虚警率都将随需检测帧数的增大而减小。

| Abstract: | Detection probability and false alarm probability are two of the most important performance index of an infrared search and track (IRST) system. Detection probability and false alarm probability were decided by the performance of system hardware and detection algorithm, etc. The influence factors to system detection probability and false alarm probability were analyzed in this paper; the model of relationship between pipeline detection, detection probability and false alarm probability was established; the influence of pipeline detection to system detection probability and false alarm probability were studied. The simulation was conducted and the experiment results were analyzed. The system total detection probability or total false alarm probability will increase when the single frame detection probability or single frame false alarm probability increase, respectively. If the pipeline length is fixed, system total detection probability and total false alarm probability will decrease when the number of required detection frames increase. |
