摘要：

在实际应用中，单波束相控阵雷达分时生成多个方向的波束，对多个目标进行照射并跟踪．针对该问题，笔者提出了一种时间资源与波束宽度联合管理算法，以节约雷达用于跟踪的时间资源．文中以概率密度函数描述雷达对目标的跟踪误差，综合考虑了雷达对目标的测距与测速精度的影响．采用最优化的方法，对雷达照射目标的驻留时间与波束宽度进行求解．仿真结果表明，相对于传统的自适应调整时间资源的方法，文中提出的方法在保证跟踪精度符合要求的条件下，能够有效地节约雷达用于跟踪的时间资源．

关键词: 相控阵雷达, 雷达资源管理, 波束宽度

Abstract:

In practical applications, single beam phased array radar can generate multiple directional beams and illuminate multiple targets, respectively. In this paper, we put forward a time-resource and the beam-width-of-joint-management algorithm to save the time resources. This paper describes the tracking precision of the target with the probability density function, and the ranging and velocity precision of the measurement will influence the tracking error. This paper uses the method of optimization to allocate the dwell time and beam width for each target. Simulation results show that, compared with the traditional adaptive methods of resource management, the method in this paper will guarantee the tracking accuracy and save the time resources for traking targets effectively, and will increase the maximum number of the targets the radar can track with the same tracking accuracy.

Key words: phased array radar, radar resource management, beam width
