摘要
塔康系统是近程军用无线电导航系统,针对现有机载塔康设备存在的测距跳变、无效和精度超差问题,分析了问题原因,介绍了塔康测距工作原理,结合综合化架构下的通信导航识别系统,提出了一种综合化机载塔康测距的双天线分集接收设计与实现方案,该方案介绍了综合化架构下的塔康功能方案构成,设计了双天线分集接收工作流程,分析了双天线分集接收的数据选择策略,提出并实现了基于测量结果决策级数据选择策略,采用卡尔曼滤波进行最优估计,通过比较距离预测残差,实时输出最优结果,解决了以往机载塔康天线切换的局限性及其存在的问题,并在实际工程中获得较好的应用。
TACAN system is near range military radio navigation system,aim at the problem of jump、invalid and accuracy error of airborne TACAN ranging,the cause of problem is analysed,the operating principle of TACAN ranging is introduced.Fall together the integrated communication navigation and identification system,a plan of double antennas diversity receiving design and implementation for the integrated airborne TACAN ranging is raised.In the plan,the constitution of integrated airborne TACAN is introduced,the working process of double antennas diversity receiving is designed,the data selection strategy of double antennas diversity receiving is analysed,the strategy of decision-level data selection based on measurement results is raised and implemented,the optimum estimation with Kalman filter is used in strategy,the optimum results is output by comparing prediction residual of the distance,solve limitations and problem of the handoff of antennas of airborne TACAN ranging,and it has been successfully utilized in engineering practice.
