BM早期预警相控阵雷达跟踪能力分析

弹道导弹（BM）跟踪是BM防御中的关键问题,分析BM早期预警相控阵雷达的跟踪能力具有重要意义。文章首先分析了预警体系中各传感器单元间的信息流程,解算了早期预警雷达与后续跟踪雷达交接班的需求特性,在分析早期相控阵预警雷达的工作流程的基础上,解算了不同距离需求时雷达可分配跟踪波束数目,给出最大跟踪能力模型,并对比常规的波束控制模式,仿真计算了两种波束分配模式下雷达的稳定跟踪能力。通过Matlab仿真结果分析,验证了雷达对BM目标的跟踪能力。

Tracking Ability Analysis of Phased-array Radar for BM Early-warning

Phased-array radar for ballistic target early-warning plays an important function in the strategic early-warning system.Firstly,this paper analyzes the information process of each unit in the early-warning system and the practice flow of phased-array radar for early-warning.In consideration of the demand characteristic of the handing-over between phased-array radar for early-warning and the following unit,this paper analyzes the amount of available tracking beam,puts forward a model to calculate the top ability of tracking and compares the ability of two assumed models.Computer simulation is conducted to compare the tracing performances of the two methods.The result shows that beam control strategy can affect the performance of the phased-array radar for early-warning.
