在连续波功率输出之外还具有一种附加能力的双模工作的概念是在单一电子对抗系统里能体现出阻塞式干扰和欺骗性干扰二者共存的优越性。由行波管实现双模工作的通常方法是用一个双管链,该双管链由一个连续波激励管和一个对脉冲功率输出为低增益透明的(trans-parent)输出管所组成。这种方法可给出连续波和脉冲工作;然而,对这种方法有一些苛刻的限制。利用一个能工作在两种模式的单一高增益行波管实现双模系统工作的新方法,最近已在休斯公司电子动力部作了估算。双模工作的单 The concept of dual-mode operation with an additional capability in addition to continuous-wave power output is the combination of blocking and fraudulent interference in a single electronic countermeasure system. A common approach to dual mode operation with TWTs is to use a dual tube chain consisting of a continuous wave excitation tube and a trans-parent output tube with pulsed power output. This method gives continuous wave and pulse operation; however, there are some harsh restrictions on this method. A new approach to dual-mode system operation using a single high-gain TWT capable of operating in both modes was recently estimated at Hughes’ Division of Electronic Power. Single-mode work
