Resource Allocation Algorithm of Velocity Estimation for MIMO Radar

Abstract

We propose a resource allocation algorithm combining transmit power and signal effective time-width joint optimization to improve the multi-target tracking performance and to achieve better accuracy of velocity estimation under the condition of limited system resources for MIMO radar. An optimization mode is established with two optimal parameters: the transmit power and the effective time of the signal to minimize the CRLB and solve this nonconvex optimization model by the sequential parameter convex estimation (SPCA) algorithm. Simulation results show that the proposed algorithm can significantly improve the estimation accuracy of target velocity and the effect on the accuracy of target velocity estimation of signal effective time-width is more than that of the transmitted power.
