这个改进的广义符号检验处理器是一个用于二维雷达的非参量的自适应检测器。这个检测器通过和邻近的采样比较来把待检验的采样符号化(即求“秩”),并用双极点滤波器来作脉间积累(即作“秩和”运算),累积的输出超过两个门限时判为有目标。第一个门限是固定的,当相邻的采样是独立的和同分布时,其虚警概率为10~(-6)。第二个门限是自适应的,当采样是累积相关的或背景是非均匀的(如:有附加目标)时候,它保持一个低的虚警率。用蒙特卡罗技术给出了这个检测器的虚警概率的结果、检测概率曲线和角精度曲线。这个检测器已经制成了,PPI(平面位置显示)照片显示了雷达工作在地物杂波背景时它的性能。
The improved generalized symbol test processor is a non-parametric adaptive detector for two-dimensional radar. This detector symbolizes the samples to be examined (ie, “rank ”) by comparing it to neighboring samples and accumulates the pulses (ie makes a “rank sum” operation) using a two-pole filter The output exceeds the two thresholds as a target. The first threshold is fixed. When the adjacent samples are independent and identically distributed, the false alarm probability is 10 -6. The second threshold is adaptive and maintains a low false alarm rate when the samples are cumulatively correlated or the background is non-uniform (eg, with additional targets). Using Monte Carlo technique, the false alarm probability of this detector is given, and the probabilistic curve and angular accuracy curve are given. This detector has been made and the PPI (Plane Position Display) photograph shows the performance of the radar when it operates on clutter.
