Measuring the target range and relative velocity in UWB radar for automobile applications

Abstract

In this paper, we present the optimal parameters such as the number of coherent integration and non-coherent integration of non-coherent signal detector under the maximum relative velocity of 120km/hr. Also we propose the arc tangent frequency difference detection (FDD) algorithm for measuring the Doppler shift. The algorithm has superior capabilities in comparison with the conventional FFT method in the accuracy, the hardware complexity, and the velocity range. © 2011 ASCE.
