Performance Improvement of Radar Target Detection by Wavelet-based Denoising Methods
With progress in radar systems, a number of methods have been developed for signal processing and detection in radars. A number of modern radar signal processing methods use time-frequency transforms, especially the wavelet transform (WT) which is a well-known linear transform. The interference canceling is one of the most important applications of the wavelet transform. In Ad-hoc detection met...

متن کاملWavelets and Neural Networks for Radar
We introduce the signals found in radar systems, and how the information they contain about targets can be used for fuzing. We then describe a new wavelet-based model for the random radar reflections from the ocean surface, which are a major source of noise in naval operations. Next we show ways of improving the performance of wavelet denoising when the corrupting noise is fractal. We then desc...
متن کاملRadar signal detection using wavelet thresholding
Abstract The purpose of the research is to study the effect of wavelet-based denoising (WBD) technique in radar signal processing. In this paper, Block thresholding is used for WBD and its performance is compared with general MTI filter by simulation and experimental results. The comparisons which are based upon ROC and visual inspection of the resulting signals are accomplished for different D...
متن کاملA Soft-Input Soft-Output Target Detection Algorithm for Passive Radar
Abstract: This paper proposes a novel scheme for multi-static passive radar processing, based on soft-input soft-output processing and Bayesian sparse estimation. In this scheme, each receiver estimates the probability of target presence based on its received signal and the prior information received from a central processor. The resulting posterior target probabilities are transmitted to the c...
