Robust序贯检测及窄带随机相位信号的Robust M-检测

Robust Sequential Detection and Robust M-Detection of Random Phase Narrow-Band Signals

Robust检测是信号检测的一个新分支,不仅可用于已知信号的检测,还可用于随机信号与随机参量信号的检测等方面.本文首先讨论将序贯检测方式引入有限样本的Robust检测,导出Robust序贯概率比检测器RSPRT,证明其具有提高信号处理速度和节约平均样本等优点.本文还针对雷达和声纳系统常遇到的窄带随机相位信号,研究如何利用位置参数M-估计方法和理论,导出了窄带随机相位信号的Robust M-检测器,经过计算机模拟证明具有良好的Robust性.

In the first part of this paper,we discuss the application of sequential detection to the Robust detection of finite sample, and derive Robust sequential probability ratio detector RSPRT.It proves that by using RSPRT,we can increase the rate of signal processing and saves the average samples.The second part investigates the problem of how to ultilize the method and theory of the M-estimation of location parameter to derive the Robust M-detector for the narrow band random phase signal commonly encountered in radar and sonar systems.
