摘要:
针对集中式MIMO雷达执行多目标跟踪任务时,现有功率分配算法计算量较大且准确性较差的问题,提出了基于认知跟踪的集中式MIMO雷达功率分配算法。该算法首先对各目标位置误差的后验克拉美罗下界进行预测,而后将预测值作为代价函数构建优化模型,从而将功率分配问题转化为凸优化问题,最后运用SDP算法进行求解。仿真实验表明,所提算法在不同场景下均能有效提升目标跟踪精度,表现出了良好的鲁棒性。
Abstract:
In order to solve the problem that the existing power allocation algorithm had a large amount of computation and poor accuracy when the centralized MIMO radar performs multi-target tracking task, a centralized MIMO radar power allocation algorithm based on cognitive tracking was proposed. This algorithm first predicts the Posterior Cramer-Rao Lower Bound of each target position error, and then took the predicted value as the cost function to construct the optimization model, so as to transform the power distribution problem into a convex optimization problem, and finally used the SDP algorithm to solve the problem. Simulation results showed that the proposed algorithm could improve the target tracking accuracy in different scenarios and good robustness.
