相控阵雷达系统最大跟踪能力研究

Maximum tracking capacity of phased-array radar system

摘要:

相控阵雷达系统的最大跟踪能力是相控阵系统的重要指标，也是边跟踪边搜索(TAS)工作模式的研究基础。为了从工程应用的角度深入分析该性能指标，本文在Singer模型基础上，分析雷达跟踪的重访时间与工程测角误差的关系，并且分析在最小检测信噪比(SNR)情况下的跟踪驻留时间。通过对多目标时的统计分析，给出了平均重访时间和平均驻留时间，在此基础上，给出稳态时的最大跟踪能力闭和解析式。最后对非稳态的情况进行了分析，得到相应的雷达饱和状态解析式。基于上述分析，利用VC++建立仿真平台，通过仿真验证了相关结论的正确性。

Abstract:

Maximum tracking capacity of phased-array radar is not only a key system index, but also the base of Track-And-Search(TAS) mode. In order to analyze the parameter from an engineering aspect, firstly, the relationship between revisit-time and engineering measurement error was researched, and tracking illuminating time with minimum Signal to Noise Ratio(SNR) requirement was analyzed in detail with the assumption of Singer model. Secondly, with the help of statistic analysis under multi-target environment, the statistic mean revisit-time and the statistic mean illuminating time were given to compute the maximum tracking capacity of phased array radar under saturation state. Furthermore, a formula was given to compute dynamic tracking under radar saturation state. Lastly, a simulation software was developed by VC++ and the related conclusions were validated on the simulation software.
