摘要：

在分布式多输入多输出(multiple input multiple output, MIMO)雷达执行目标检测和跟踪多任务时, 为了在多个目标中突出对重点目标的跟踪, 提出了基于改进公平起点搜索的阵元选取模型与求解算法。在限定目标检测性能、跟踪性能和系统资源的前提下, 以最小的阵元集合为代价函数, 建立优化模型。为在同一框架下讨论系统的不同性能指标, 对参数进行预处理, 将表征跟踪性能的位置估计误差界进行去量纲化、归一化处理。分别引入表征目标重要程度和任务重要程度的权重因子, 得到表征系统综合性能的参数。遍历每一个初始阵元对, 逐次增加对系统贡献最大的阵元, 最终完成阵元集的选择。仿真结果表明, 所提算法能够提供接近穷举算法的性能并有效降低系统计算量。

Abstract:

In order to highlight the tracking performance of key targets in multiple targets, the algorithm of model establishment of antenna selection and its solution based on modified fair multi-start local search is proposed for antenna selection of distributed multiple input multiple output (MIMO) radar under the multitask of target detection and tracking. On the premise of limiting the target detection performance, tracking performance and system resources, the optimization model is established with the minimum set of antennas as the cost function. In order to discuss the different performance indexes of the system in the same framework, the parameter preprocessing is carried out, and the position estimation error bounds of targets which represent the performance of target tracking are non-dimensionalized and normalized. The weight factors of the target importance and task importance are introduced to get the parameter of the comprehensive performance of the system. Traverse each initial antennas set, the antenna that contribute the most to the system is added step by step, and finally complete the selection of antennas set. The simulation results show that the proposed algorithm can provide the performance that near exhaustive algorithm and effectively reduce the system computation.

Key words: distributed multiple input multiple output (MIMO) radar, resource allocation, multitask, key targets
