Using the system optimization method, designed the X band DRO, which reached the desired specification. 利用优化的系统设计方法,根据测速雷达对信号源的要求,设计的X波段介质振荡器达到了预定的设计指标。
The effects of radiation and absorption of raindrops on S and X band radar electromagnetic waves are compared and discussed in this paper. 本文讨论雨滴对船用雷达的两个波段，即S波段和X波段雷达电波的辐射和吸收作用，并且对辐射和吸收作用作出比较，对S波段和X波段的作用也作出了比较。结果表明雨滴对X波段的雷达电波的辐射作用较吸收作用为大，雨滴对X波段的雷达电波的吸收作用较对S波段的雷达电波的吸收作用为大。
With the two-dimension fully electromagnetic Particle-in-cell(PIC) simulation, the output power of 1.16GW at C band and 270MW at X band in MILO were obtained. 用在阴极端头增加发射电流的办法，在C波段理论得到了1.;16GW的微波输出功率。利用增加高次谐波的办法在X波段理论获得了270MW的输出功率。
At X band,its advantages are especially useful. In this work, a mathematical model used to optimize DAW (without supports) cavities by SUPERFISH was built and the solution was presented. 给出了利用SUPERFISH程序进行腔形优化的数学模型以及利用该模型对X波段DAW结构的优化设计结果 .
