摘要：

针对复合高斯杂波中的子空间信号检测，研究了广义似然比检测器和恒虚警检测器。针对检测统计量分布特性非常复杂、难以获得检测概率解析式的问题，通过对检测统计量的分布特性做合理近似，推导了检测概率的近似解析式，为检测性能的分析和评估提供了便利。然后以悬停直升机的检测为例，验证了近似解析式的准确性，并分析了检测概率与信号参数的关系。

Abstract:

The detection of subspace signal in compoundGaussian clutter is investigated by the generalized likelihood ratio test and constant false alarm rate detectors. Since the statistical distribution of the test statistics is very complicate, an analytical expression for the detection probability is usually infeasible. Employing a reasonable approximation to the distribution of the test statistics, an approximate close form expression for the detection probability is derived, which will facilitate the analysis and evaluation of detection performance. Finally, using the detection of hovering helicopters as an example, the accuracy of the approximate close form results for the detection probability is verified, and the detection performance with regards to the signal parameters is analyzed.
