Yang Li, Zhenghe Feng, Yanhong Xiao, Jingyu Huang · 2003
An artificial neural network method for signal processing of LFMCW or LFSCW is proposed. It is based on decomposition of autocorrelation matrix. The decomposition problem is mapped into an iterative one by transforming the energy function of the Hopfield neural network. Simulation and experimental results show that this method has resolution higher than the theoretical limit of the FFT method and other popular algorithms and its SNR threshold is lower.
