本文研究了在窄带稳态高斯杂波背景和X~2分布目标模型下的测检器性能,导出了检测概率的通用公式和便于计算的递推算法表示式。计算结果表明,当参考单元中存在目标信号时,虚警概率随着信杂比的增加而迅速降低,检测概率也明显下降。当目标的起伏程度不同时,检测器的性能也不同。文中还提出了减小参考单元中目标信号对检测性能影响的基本自适应方案。
In this paper, the performance of the detector under narrow-band steady-state Gaussian clutter background and X ~ 2 distribution target model is studied. The general formula of detection probability and the recursive algorithm representation for calculation are derived. The results show that when there is a target signal in the reference cell, the false alarm probability decreases rapidly with the increase of signal-to-noise ratio, and the detection probability decreases obviously. The performance of the detector is also different when the degree of undulation of the target is different. The paper also proposes a basic adaptive scheme to reduce the influence of the target signal in the reference cell on the detection performance.
