用于高功率雷达系统的冷阴极分布发射正交场放大器,由于起动延迟、功率跌落,电路损耗和低效率等因素而导致器件性能变坏。美国陆军电子发展部门对此作了理论分析,解释了使器件性能恶化的原因,其关键在于正交场放大器空间电荷流的全部性能,它可以用二个与时间无关的参数,即阴极平均二次发射系数和电子平均回轰能量加以完整地说明,而这些参数表示了阴极发射能力的特征,并随着器件互作用空间的几何形状、工作条件和阴极材料的改变而变化,为改进正交场放大器的性能,可将理论分析进行程序编制,应用数字计算机作为设计和计算的工具。
Cold cathode-distributed transmitting orthogonal field amplifiers for high power radar systems deteriorate device performance due to factors such as start-up delay, power drop, circuit loss and inefficiency. The United States Army Electronics Development Department made a theoretical analysis of this, explains the reasons for deteriorating the performance of the device, the key lies in the orthogonal field amplifier space charge flow of the full performance, it can be used with two time-independent parameters, namely, The secondary emission coefficient and the electron average back-bomb energy are fully described, and these parameters indicate the characteristics of the cathode emission capability, which varies with the geometry of the device interaction space, the working conditions and the change of the cathode material. In order to improve the quadrature Field amplifier performance, theoretical analysis can be programmed, the use of digital computers as a design and calculation tool.
