Abstract TN957; 该文针对异步多目标跟踪场景,研究了非理想检测下的异构多雷达网络功率时间联合优化问题.首先,将各融合采样间隔内得到的来自不同雷达节点的所有异步量测信息融合为复合量测信息,结合该复合量测信息推导了非理想检测下包含雷达节点选择、辐射功率和驻留时间等参数的异步目标跟踪误差贝叶斯克拉美罗下界(BCRLB)解析表达式,并将其作为异步多目标跟踪精度的衡量指标.在此基础上,建立了非理想检测下面向异步多目标跟踪的异构多雷达网络功率时间联合优化模型,即以最小化异步多目标跟踪误差为优化目标,以满足给定的系统辐射资源限制为约束条件,对不同雷达网络中雷达节点的选择方式、辐射功率和驻留时间等发射参数进行自适应联合优化设计,从而提升异构多雷达网络的异步多目标跟踪精度.最后,针对上述优化问题,结合序列二次规划(SQP)算法和循环最小法,采用四步分解算法进行求解.仿真结果表明,与现有算法相比,所提算法能够有效提升异构多雷达网络的异步多目标跟踪精度.
