本文首次提出将测向与空域滤波相结合,使该系统既可测向,又具有高质量通信的功能;不仅可以用于机场测向,也可用于通信干扰侦察。该系统如果再配置接收机,频谱分析仪,还可用于监听瞬时测频。 This paper proposes for the first time the combination of DF and airspace filtering so that the system can not only detect but also has the function of high quality communication. It can be used not only for DFR but also for communication interference reconnaissance. The system if you configure the receiver, spectrum analyzer, can also be used to monitor the instantaneous frequency measurement.
