低信噪比信号检测一直都是侦察领域关注的课题。为此,提出了基于相关算法的脉冲信号检测方法,介绍了相关算法检测原理,用统计分析方法确定了理论最佳检测门限,并对相关检测性能进行了仿真分析,在低信噪比条件下完成了信号到达时刻和脉冲宽度的估计。
Signal detection in low signal to noise ratio（SNR） is always the attentive subject in reconnaissance field. This paper presents a pulse signal detection method based on correlation algorithm, and introduces the detection principle of correlation algorithm, uses statistical analysis method to determine the theoretical detection threshold, makes simulation analysis for correlation detection performance, and completes the estimation of signal arrival time and pulse width in low SNR.
