摘　　要：针对突发信号检测问题,分别建立了实信号检测和复信号检测的二元假设检验模型,基于线性模型广义似然比检验构建了检验统计量,得出了两种假设条件下检验统计量的概率分布函数,并根据检验统计量的概率分布函数推导出了检测器性能的解析表达式。用仿真的方法对推导结果进行了验证,仿真结果和理论结果完全一致。To address the problem of burst signal detection,binary hypothesis testing models for real signal detection and complex signal detection are established respectively.A test statistic is constructed based on the generalized likelihood ratio testing method of linear model,the probability distribution function under two assumptions is obtained,and an analytical expression of detector performance is derived from the probability distribution function of the test statistic.Simulation method is employed to verify the performance of the detector and the simulation results are consistent with the theoretical results.
