本文研究了相对论返波管产生X波段超辐射问题,产生中心频率为9.25 GHz的电磁脉冲,并在相对论返波管的输出端直接接入VLASOV辐射天线.提出将粒子模拟软件UNIPIC与自行研制的天线辐射模块相结合,实现超辐射现象微波的产生以及辐射的全过程模拟,并研究了输出功率随注入波脉冲以及填充稀有气体气压的变化.模拟结果表明,器件的峰值功率可以达到3.68 GW,瞬时效率超过100%,VLASOV天线在斜切角为20?时,天线的增益达到15.5 dB,在1 km处的功率密度可达到0.728 W/cm2.
In this paper, the problem of X-band superradiation in the relativistic backwave tube was studied, and the electromagnetic pulse with the center frequency of 9.25 GHz was generated, and the VLASOV radiation antenna was directly connected to the output of the relativistic backwave tube.The particle simulation software UNIPIC and self-developed Antenna radiation module to achieve the generation of super-radiation microwave and the whole process of radiation simulation, and study the output power with the impulse wave filling and filling of rare gas pressure changes.The simulation results show that the peak power of the device can reach 3.68 GW, With an instantaneous efficiency of over 100%, the gain of the antenna reaches 15.5 dB at a chamfer angle of 20 Ω for the VLASOV antenna and 0.728 W / cm 2 at 1 km.
