| 摘 要： | 被动探测中，低信噪比下检测信号的方法备受关注。本文讨论基于总和的检测方法。采用该方法就能将信号和噪声在时域中区分开来，并能较精确地确定信号的起止时刻。该方法具有实时性好、检测概率高的特点。仿真结果表明这种方法切实可行。

| Abstract: | Signal detection under low signal-noise ratio in passive detection is increasingly needed.A detection method based on accumulation is presented in this paper.The useable signals can be distinguished accurately from noise through this method in time domain;and signals arriving and ending time can be estimated correctly.The method brings highly real-time detection and high detection probability.Simulation results show that it is feasible. |
