| 摘 要： | 本文从理论上研究了采用自适应逆谱(或白化)滤波器级联匹配滤波器构成的自适应检测器的性能,着重分析了背景噪声AR参数估值误差对检测性能的影响。以两种典型的信号型式(宽带、窄带)为例的分析计算表明,这类检测器的检测性能对参数估值误差并不敏感。因而自适应逆谱(或白化)滤波器级联适当的匹配滤波器方案是一种有用的自适应检测器方案。

| Abstract: | The performnce function of an adaptive detector composed of an adaptive inverse spectrum (or whitening) filter and a matched filter is derived. Effects of AR parameter estimation errors on the detection performance is analysed. Computation results for the AR noise with order 1, 2, 3 and two typical signal forms (narrow-band and wide-band) indicate that the detection performance of this kind of adaptive detectors is not sensitive to the AR parameter estimation errors. In addition another advantage of this kind of adaptive detectors, it is useful to the practice applications. |
