摘要
预警机中存在的辐射源众多,单个辐射源工作时,与其同频段同极化的低灵敏度接收设备一般采取分时工作或模拟干扰抵消,而多个辐射源同时工作时,目前还无有效的解决方案。提出了一种宽带数字射频干扰抵消技术,以解决预警机中多源共址干扰的问题。
There are many radiation sources in early warning aircraft.While a single radiation source works,the low-sensitivity receiving equipments with the same frequency band and the same polarization mode usually adopts the modes of time sharing or analog interference cancellation.While multiple radiation sources work,there is no effective solution.This paper proposes a wideband digital radio frequency(RF)interference cancellation technique to solve the problem of multi-source co-location interference in early warning aircraft.
