Tunable Multichannel Adaptive Detector for Mismatched Subspace Signals

摘要

摘要: 针对存在信号失配时的子空间信号检测问题，该文提出一种具有恒虚警特性的参数可调检测器。根据系统设计需要，通过调节参数，参数可调检测器可实现对失配信号的灵活检测。与现有检测器相比，当不存在信号失配时，提出的可调检测器能提供更高的检测概率。该文推导了可调检测器解析的检测概率和虚警概率，并通过蒙特卡洛仿真进行了验证。

Abstract: For the detection issue in the presence of subspace signal mismatch, a parametrically tunable detector is proposed, which processes the Constant False Alarm Rate (CFAR) properties. By changing the tunable parameter, the proposed detector can flexibly detect the mismatched subspace signal. Moreover, in the case of no signal mismatch, the proposed tunable detector can even achieve better detection performance than the existing detectors. The expressions for the probabilities of detection and false alarm are proposed and verified with Monte Carlo simulations.
