中文摘要：

针对有用信号存在失配条件下的自适应检测问题,该文提出了一种新的参数化自适应检测器。对失配信号稳健的自适应匹配滤波器,或对失配信号敏感的双归一化自适应匹配滤波器都可以作为该检测器的一种特例,并可以利用参数控制检测器对失配信号的检测能力和对干扰信号的抑制能力。推导了该检测器的虚警概率和对失配信号的检测概率。计算机仿真分析表明,通过选择合适的参数,可以保证该检测器对少许失配的有用信号的检测性能,以及对严重失配的干扰信号的抑制性能。

英文摘要：

The adaptive detection problem for mismatched useful signal is considered. A novel parametric adaptive detector is proposed, and the adaptive matched filter and double normalized adaptive matched filter are the special cases of the tunable detector. The detector parameters can be used to control the detection performance for slight mismatched signal and rejection performance for serious mismatched interference. The probability of false alarm and the probability of detection for mismatched signal are derived. The computer simulation results show that we can choose suitable parameter to control the ability to detect mismatched useful signal and the ability to reject interference.
