Tunable Multichannel Adaptive Detector for Mismatched Subspace Signals

  • 摘要: 針對存在信號失配時的子空間信號檢測問題，該文提出一種具有恒虛警特性的參數可調檢測器。根據系統(tǒng)設計需要，通過調節(jié)參數，參數可調檢測器可實現對失配信號的靈活檢測。與現有檢測器相比，當不存在信號失配時，提出的可調檢測器能提供更高的檢測概率。該文推導了可調檢測器解析的檢測概率和虛警概率，并通過蒙特卡洛仿真進行了驗證。
    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.
