| 摘 要： | 机载相控阵雷达在探测远程、低空、高速目标时具有较大潜力。本文对机扫加相扫雷达环境下,如何充分发挥相控阵优势,提高机载雷达跟踪远程低空高速目标性能展开研究,在传统边扫边跟(Track while scan,TWS)技术基础上,给出了一种基于目标威胁度的快速确认跟踪模式。该模式采用有效的相控扫描策略,充分利用其波束捷变能力,通过相控回扫,一方面快速起始航迹,增加高威胁目标的跟踪距离;另一方面适当增加探测数据率,提高对远距高威胁目标的跟踪性能。仿真试验表明,新跟踪方法不但可以较好克服目标雷达散射截面积(Radarcross section,RCS)起伏影响,较快地起始和跟踪目标航迹,而且保留了TWS方法覆盖空域广的优点。

| Abstract: | Airborne phased array radar which provides electronic and mechanical scanning capabilities has the potential to track those targets with low altitude,high speed and long range.In order to exploit beam agility to improve the tracking performance of phased array radars,a novel target tracking method with rapid confirmation is proposed based on the conventional track while scan(TWS).Effective electronic scanning strategies are applied to enlarge tracking range by rapidly confirming initialization of track and ... |
