An extended Neyman–Pearson detector based on the combination of a traditional matched and wavelet filter in pulsed monostatic radar was proposed in this paper. Its properties were compared with properties of the cell average constant false alarm radar detector in the presence of white noise. The properties of detectors were examined in the receiver operating characteristic curves, parameter space. It consisted of false detection rate and the rate of true positive detected targets. In order to investigate the influence of temperature, the new parameter space was constructed: the temperature versus the rate of true positive detected targets. The traditional Neyman–Pearson detector based on a matched filter was fully operational and superior in the temperature range between 290K and 350K. Below this temperature range, its performance is completely degraded. It has been shown that by adding a wavelet filter, it can extend this temperature range between 260K and 350K. In the temperature range, where all detectors are fully operational, extended and classic Neyman–Pearson detectors had better performance than constant false alarm radar detector in the receiver operating characteristic curves’ parameter space.

单基地脉冲雷达中扩展 Neyman-Pearson 探测器的计算机仿真

本文提出了一种基于传统匹配和小波滤波器相结合的脉冲单基地雷达扩展Neyman-Pearson检测器。将其特性与存在白噪声时的小区平均常数虚警雷达探测器的特性进行了比较。在接收器操作特性曲线、参数空间中检查检测器的特性。它由错误检测率和真阳性检测目标率组成。为了研究温度的影响，构建了新的参数空间：温度与真阳性检测目标的比率。基于匹配滤波器的传统 Neyman-Pearson 检测器在 290K 和 350K.低于此温度范围，其性能完全下降。已经表明，通过添加小波滤波器，它可以将这个温度范围扩展到 260K 和 350K. 在所有探测器完全运行的温度范围内，扩展和经典的 Neyman-Pearson 探测器在接收器工作特性曲线的参数空间中比恒定虚警雷达探测器具有更好的性能。
