摘　　要：提出了一种用于对无人机进行电子侦测的覆盖0.4~8.0 GHz超宽带微波接收机,具有异步搜索和同步跟踪的功能。该超宽带接收机采用两次变频体制,所采用第一本振为宽带本振,通过单刀双掷开关选择同步本振或异步本振作为第一本振,第二本振采用固定本振。该超宽带微波接收机具有平坦度低、杂散小、交调低、抗外界干扰能力强,且具有并行搜索信号能力和高精度侧向跟踪能力的特点。A type of ultra-wideband(UWB)receiver covering 0.4~8.0 GHz for electronic reconnaissance of unmanned aerial vehicles(UAVs)was proposed in this paper,which had the functions of asynchronous searching and synchronous tracking. The new UWB receiver adopts a two-frequency conversion system. The first oscillator is a wideband local oscillator,and the synchronous or asynchronous oscillator is selected as the first oscillator through a single-pole and double-throw(SPDT)switch,while the second oscillator is a fixed local oscillator. The ultra-wideband microwave receiver has the characteristics of small spurs,low cross and strong ability to resist external interference,and it has the characteristics of parallel searching signal ability and high precision lateral tracking ability.
