In the past or nowadays, the radar reconnaissance receiver always plays an important role in electronic-war (EW).
由于雷达侦察接收机面临的是未知的信号环境，甚至接收的电磁信号是专门设计以避免被侦察截获的，因此，随着电子战信号的日益密集，信号形式的日益复杂，传统的由一套测频系统加一套阵列测向系统构成的电子侦察设备日益复杂，并且难以满足现代电子战对侦察设备功能以及性能上的要求，迫切需要研制集成化、小型化、功能强大的适应现代电子战环境的新体制雷达侦察接收机，以时空二维谱估计技术为理论基础的测频测向一体化新体制雷达侦察接收机正是这一发展方向的典型代表之一。
