针对组网协同多输入多输出(C-MIMO)雷达系统，提出了一种联合雷达调度和波束方向图设计(JRSBD)策略来跟踪杂波中的多个目标。该机制通过联合优化各C-MIMO雷达的雷达调度和波形相关矩阵，使跟踪性能最大化。首先，我们提出了确定性协方差作为性能度量，来量化实际目标状态估计的精度。其次，将JRSBD策略描述为具有一定系统约束的优化问题。由此产生的优化问题既包含二元变量，也包含连续变量，并且是非凸的。最后，提出了一种求解该问题的序列凸规划方法。数值仿真结果表明，JRSBD策略能有效提高目标跟踪精度。
In this letter, a joint radar scheduling and beampattern design (JRSBD) strategy is proposed to track multiple targets by a netted colocated multiple-input multiple-output (C-MIMO) radar system in clutter. The mechanism is to jointly optimize the radar scheduling and the waveform correlation matrix of each C-MIMO radar to maximize the tracking performance. First, we develop the deterministic covariance, as the performance metric, to quantify the actual target state estimate accuracy. Second, the JRSBD strategy is formulated as an optimization problem with some system constraints. The resulting optimization problem contains both binary and continuous variables and is nonconvex. Finally, we propose a sequential convex programming method to solve it. Numerical simulations demonstrate that the JRSBD strategy can effectively improve the target tracking accuracy.
