FMCW radar with multiple initial frequencies for robust source number estimation

Abstract

<p>We propose a novel method to estimate source number used in Direction Of Arrival (DOA) estimator for Frequency Modulated Continuous Wave - Multiple-Input Multiple-Output (FMCW-MIMO) radar. The main principle is that the phase of the intermediate signals can be modified by the initial frequency of transmitted signals. We confirmed that our method can distinguish true and spurious sources when the number of sources is larger than the number of true sources.</p>
