Comparative Analysis of Matched Filter and Wavelets for Radar Noise Reduction
Keywords:
Denoising, matched filter, radar noise, SNR, wavelets.Abstract
This paper compares Matched filter and Wavelet
transform applied to both Continuous Wave Radar and Pulse
Radar signals to reduce the noise. For removing noise and
extracting signal, Wavelet analysis is one of the most important
methods. The denoising application of the wavelets has been
used in spectrum cleaning of the atmospheric radar signals.
Matched filter has strong anti-noise ability; it can also achieve
accurate pulse compression in a very noisy environment. This
paper analyzes the algorithms of Matched filter and Wavelets
that are used in radar signal processing to reduce the noise. The
simulation results indicate that Matched filter has strong
anti-noise ability for Pulse Radar and Wavelet for Continuous
Wave Radar.
