摘要
结合工程实际需要,在不考虑其他因素对目标检测概率影响的情况下,对不同的逻辑准则,根据状态转移法,分析和计算了逻辑法航迹起始概率随雷达扫描周期数的变化情况,并据此计算了4种典型逻辑准则下航迹起始所需要的平均扫描周期数。给出了在恒虚警率条件下虚假航迹率计算方法,并对4种典型逻辑准则下的虚假航迹率与扫描周期数的关系进行了仿真。提出了噪声背景下的航迹起始概率计算方法,并给出了恒虚警率检测条件下航迹起始概率随信噪比变化曲线。
According to actual engineering requirements and the state transition method, without considering the effect of other factors on the target detection probability, the variations of the initial probability of track with the logic method with the number of scanning period are analyzed and calcu- lated for different logic rules, on the basis of which the average number of scanning period required for the track initiation is calculated under four typical logic rules. The method of calculating the false track probability is given on the CFAR condition, and the relations between the false track probabili- ty and the number of scanning period are simulated under four typical logic rules. The method of calculating the initial probability of track is presented on the noise background, and the variation curves of the initial probability of track with the SNR are given on the CFAR detection condition.
