Abstract

One-dimensional data obtained by performing a Fourier transform on a digitally converted frequency modulated continuous wave (FMCW) radar signal at every pulse repetition interval is input to a recurrent neural network (RNN) to find the probability of the existence of a target in each range index. The range indices, i.e., bit frequencies are selected based on the probability. In order to reduce the size of the RNN, windowing may be applied. In addition, a speed-index-specific coefficient value may be calculated by accumulating and performing a Fourier transform on the selected bit frequencies in which the target exists over a plurality of pulse repetition intervals. Thus, it is possible to calculate the speed of the target.
