| 摘 要： | 对两种高功率微波传输与发射系统进行了研究、比较，其中，束波导传输偏置抛物面系统适用于过模波导用入．真空椭圆软波导传输抛物面系统适用于单模波导输入的情况，对以上两种发射系统进行了物理光学数值分析（ＰＯ／ＰＯ）．在Ｓ波段，在未优化设计前，前者截获效率８６．６％，增益４０ｄＢ，后者截获效率９６．７％，增益４２．５ｄＢ．

| Abstract: | Two radiating systems for generating a scanning high power microwave beam are presented. The first one uses beamwaveguide to feed an offset paraboloid antenna,which is suited for overmode input waveguide. The second consists of an offset paraboloid antenna fed by a multimode horn that is linked to a vacuum flexiable elliptical waveguide as a method of limited elevation scan, which is simple and suited for the transmitter with single mode output waveguide. The physical optics analysis technique is used to investigate above antennas.The numerical resultS shows that the gains and spillover efficiencies are reasonable. |
