摘      要：A joint resource allocation scheme concerned with the sensor subset,power and bandwidth for range-only target tracking in multiple-input multiple-output(MIMO)radar systems is *** selecting an optimal subset of sensors with the predetermined size and implementing the power allocation and bandwidth strategies among them,this algorithm can help achieving a better performance within the same resource ***,the Bayesian Cramer-Rao bound(BCRB)is derived from ***,a criterion for minimizing the BCRB at the target location among all targets tracking in a certain range is ***,the optimization problem involved with three variable vectors is formulated,which can be simplified by deriving the relationship between the optimal power allocation vector and the bandwidth allocation ***,the simplified optimization problem is solved by the cyclic minimization algorithm incorporated with the sequential parametric convex approximation(SPCA)***,the validity of the proposed method is demonstrated with simulation results.
