塔康导航系统  一种近程极坐标式无线电导航系统。它由机上发射与接收设备、显示器和地面台组成。这种系统是1952年研制成功的,它的作用距离为400~500公里,能同时测定地面台相对飞机的方位角和距离,测向原理与伏尔导航系统相似,测距原理与测距器相同,工作频段为962~1213兆赫。    从飞机上每秒发射30对、间隔为12微秒的询问脉冲对(成对发射的脉冲),地面台收到询问脉冲对后发射同样间隔的回答脉冲对。在飞机上把收到回答脉冲对的时间与询问脉冲对的时间相比较,得出脉冲电波在空间传播的时间,从而得到飞机到地面台的距离,并加以显示。地面台天线发射电波的方向图呈有 9个波瓣的心脏形,并以900转/分转动。飞机接收到的脉冲信号是调幅形式的,这一调幅包络包括由旋转心脏形方向图产生的15赫方位信号和由9个波瓣旋转产生的135赫方位信号,这两个信号的相位与地面台相对飞机的空间方位有关。为测定相位需要有基准信号,因此当心脏形方向图转过正东方向时,发射一组由12个脉冲对组成的基准脉冲信号,当8个波瓣(除去与心脏形最大值重合的那个波瓣)中每一个的最大值转过正东方向时,还发射一组由6对脉冲组成的辅助基准脉冲信号。比较15赫方位信号和基准脉冲信号的相位,得到地面台相对飞机的粗略方位,用它来消除精测方位时的多值性。比较 135赫方位信号和辅助基准脉冲信号的相位即得到地面台相对飞机精确的方位值。      塔康系统属于军用设备,但它的测距部分可作为民用测距器,因而有时将塔康和伏尔系统装在一起,组成伏尔塔克导航系统。军用飞机由塔康系统获得距离、方位信号,民用机则由伏尔系统获得方位信号,由塔康系统获得距离信号(见无线电导航、伏尔导航系统)。    塔康系统采用了多瓣技术(见飞行器天线),在系统中有精测通道,故测向精度比伏尔导航系统高。这个系统是点源系统,地面台可机动转移,在复杂地形和战时布台很方便,所以称为"战术空中导航系统"。
