欺骗性干扰场景下的功率带宽联合分配策略OA

In view of the problem of radar performance degradation caused by deceptive jamming,this study proposes a joint power and bandwidth allocation scheme to improve the radar′s detection accuracy,and utilizes the high detection performance to enhance the radar′s anti-jamming decision-making ability.The three-dimensional CRLB(Cramer-Rao Lower Bound)of the deceptive distance is used to represent the radar′s detection accuracy,and the CRLB is taken as the objective function to establish an optimization problem.Considering the limited resources,the total amount of power resources and the total amount of bandwidth resources in the optimization problem are re-stricted within a fixed range.According to the non-convex and non-linear characteristics of the resource optimization allocation problem,a solution combining the cyclic minimization algorithm and the projected gradient descent algo-rithm is proposed.Simulation experiments are carried out under different radar layouts.The simulation results show that,compared with the unoptimized allocation scheme,the CRLB value of the joint resource optimization allocation scheme is reduced by 20%to 30%,which improves the radar′s detection accuracy and alleviates the performance degradation problem caused by deceptive jamming.
