Abstract

Following the idea of correlation detection, a wide-band signal detection method that is based on two-dimensional correlation in the time-scale domain of continuous wavelet transform (CWT) is presented. The performance of this detector is analyzed by simulations and experiments. It shows that a CWT based detector has a good performance, far better than that of the energy detector, and a smaller reduction than that of the matched filter, especially at a low signal to noise ratio. This method is not only suitable for wideband acoustic signal processing, but also fit for the processing of other transient signals whose waveform and arriving time are unknown.

基于时域二维相关的宽带信号检测

根据相关检测的思想，提出了一种基于连续小波变换时间尺度域二维相关的宽带信号检测方法。通过仿真和实验分析了该探测器的性能。结果表明，基于CWT的检测器具有良好的性能，远优于能量检测器，并且比匹配滤波器的降低幅度更小，特别是在低信噪比下。该方法不仅适用于宽带声信号的处理，也适用于其他波形和到达时间未知的瞬态信号的处理。
