  Abstract

The electronic warfare support system is a crucial element of electronic warfare that detects and estimates the enemy's threat signal source and provides obtained information to friendly forces. However, since most of the threat signal sources in electronic warfare are weak signals, noise removal must be preceded to obtain information. In general, various methods for noise removal exist; among them, the method using wavelets has drawn much attention in electronic warfare support. However, this wavelet-denoising based method is challenging to use in a weak signal environment because it uses kurtosis as a threshold value in the process of distinguishing signals from noise. In addition, it is limited to the subject of signal detection and does not deal with problems that occur when estimating the detected signal parameters. Therefore, in this paper, we analyze these problems and propose time-of-arrival and pulse-width estimation methods based on change point detection to solve the problems. This method can accurately estimate even in weak signal environments regardless of the modulation scheme of the signal. Through computer simulation, we compare the performance of the proposed and conventional methods, and simulation results show that the proposed method has superior performance.
