Linear frequency modulated reverberation suppression using time series models

When active radar and <span>sonar systems are used for target detection tracking, boosting detection, tracking efficiency is the most important challenge in real-time reverberation. To eliminate reverberation when transmitting linear frequency modulated (LFM) signals, this study employs time series techniques such as autoregressive (AR), moving average (MA), (ARMA). The primary purpose of research to whiten LFM by transforming it a fractional domain using Fourier transform (FrFT). highly coloured noise whose fluctuates according stationary hitting frequency. As reference signal, proposed methods make use adjacent signal block. effectiveness FrFT-based AR, MA, ARMA pre-whitening reduction was assessed, results were presente</span>d.
