Abstract Different from conventional phased array radar, the colocated multiple-input multiple-output (MIMO) radar can form multiple beams simultaneously through transmitting orthogonal waveforms by its sub-arrays. The illuminating mode of multiple beams can be changed with the sub-array number, providing greater flexibility in system resource management. In this paper, a novel resource management optimization model for the colocated MIMO radar in multiple targets tracking is proposed, where the average time and energy resource consumption of the system are minimized under the guarantee that the illuminated targets can be effectively detected. When solving the proposed optimization problem, the adaptive simultaneous multibeam resource management (ASMRM) algorithm for the colocated MIMO radar is obtained, where the sub-array number, the beam directions, the system sampling period, the transmit waveform energy and the working mode can be controlled adaptively. Simulation results demonstrate that the working parameters of the colocated MIMO radar can be changed effectively. Furthermore, in terms of the average system resource consumption, the proposed algorithm is superior to the algorithms with fixed parameters while realizing the effective multiple targets tracking.

多目标跟踪中协同定位MIMO雷达的自适应同时多波束资源管理

摘要 与传统相控阵雷达不同，共置多输入多输出(MIMO)雷达通过其子阵发射正交波形，可以同时形成多个波束。多波束的照射方式可随子阵数量变化，为系统资源管理提供更大的灵活性。本文针对多目标跟踪中的协同定位MIMO雷达，提出了一种新的资源管理优化模型，在保证有效检测被照射目标的情况下，最小化系统的平均时间和能量资源消耗。在求解所提出的优化问题时，得到了协同定位 MIMO 雷达的自适应同步多波束资源管理 (ASMRM) 算法，其中子阵数，可自适应控制波束方向、系统采样周期、发射波形能量和工作模式。仿真结果表明，可以有效地改变共置MIMO雷达的工作参数。此外，在平均系统资源消耗方面，该算法在实现有效的多目标跟踪的同时优于固定参数的算法。
