Target Signal Detection Apparatus Using Correlation based Wavelet Signal

摘要

The present invention relates to a target signal detection device using a correlation. Especially, the present invention relates to a target signal detection device which performs sampling of a signal reflected from a target by using delay clock signals to generate a wavelet signal and detects a valid target signal by using a correlation of the wavelet signal and a reference signal. The target signal detection device of the present invention comprises: a signal receiving part receiving a reflection signal reflected from the target; a sampling part sampling the reflection signal by using different clock signals; and a digital signal processing part generating the wavelet signal through a wavelet conversion with respect to the sampled reflection signal, and correlating the wavelet signal with a pre-defined reference signal to detect the target signal reflected from the target among the reflection signal.
