Abstract
This paper analyzes the effect of waveform parameters on the joint target location and velocity estimation by non-coherent multiple-input multiple-output (MIMO) radar transmitting multiple subcarriers signals without energy constraint. How the number of subcarriers influence the estimation accuracy is illustrated by considering the joint Cramer-Rao bound (CRB) and the mean square error (MSE) of the maximum likelihood (ML) estimate. The non-coherent MIMO radar ambiguity function (AF) with multiple subcarriers is developed and investigated by changing the number of subcarriers, the pulse width and the frequency spacing between adjacent subcarriers. The numerical results show that more subcarriers means more accurate estimate and higher localization resolution, larger pulse width results in worse performance of target location estimation, while the frequency spacing affects target location estimation little.
