设计主动式电子对抗系统应具有接收宽带的输入雷达频率并立即转发一组虚假诱敌信息的能力。这种系统必须在频率、输入讯号电平和脉冲波形的宽阔变化范围内正常地工作。迄今,在倍频程内,行波管与其他类型器件比较,具有最大的增益-带宽积,据其固有特性而用于上述系统是相当理想的。行波管的其他军事应用包括有相控阵雷达、无人驾驶飞行体的制导及其遥控,火炮瞄准等方面。行波管的低噪声性能使它在需要最 Designing active electronic countermeasures systems should have the ability to receive wideband incoming radar frequencies and immediately forward a set of fake lure information. Such a system must function normally over a wide range of frequencies, input signal levels, and pulse waveforms. To date, traveling wave tubes have the largest gain-bandwidth product over the octave band compared to other types of devices and are ideal for use in such systems based on their inherent characteristics. Other military applications of traveling wave tubes include phased array radars, guidance of unmanned aerial vehicles and their remote control, artillery aiming and so on. The low noise performance of a traveling wave tube makes it most needed
