摘要
本文提出了一种基于小波变换的信号检测方法,对白噪声背景下的舰船辐射噪声(简称舰船噪声)进行了检测;推导了相应的检测统计量及其统计分布特性:并与传统的能量检测器、匹配滤波器进行了比较,计算机仿真结果证明了本方法是有效的。
Based on wavelet transform, a new method of detecting ship noise in white noise is proposed. The detection statistics based on the wavelet coefficients is given and the performance of the detector is evaluated. Comparing with the energy detector and the matched filter, computer simulations show that the proposed approach is effective.
