Beat-frequency matching for multi-target based on improved trapezoid wave with FMCW Radar

Abstract

FMCW (Frequency Modulation Continuous Wave) radar has many useful applications. In multi-target condition, the incorrect combination of the beat-frequency may occur with the classical trapezoidal wave. In this paper, a new modulation waveform based on improved trapezoidal wave and the corresponding pairing algorithm are proposed which make pairing precision greatly increased and calculated quantity drops greatly.
