| 摘 要： | 该文介绍航管二次雷达(SSR)发射天线方向图综合的新方法,这种方法以有源相控阵天线为基础。利用带底座的Cosine口径幅度分布综合出所需的定向方向图,辐射用于询问的P1和P3脉冲。在上述口径幅度分布基础上,利用驻相法获得所需的口径相位分布以综合出方位上全向的方向图,辐射用于询问旁瓣抑制(ISLS)的P2脉冲。省去了单独辐射P2脉冲的天线和相应设备。

| Abstract: | A new method of transmit pattern synthesis for Secondary Surveillance Radar (SSR) is presented. This method is concerned with an active phasedarray antenna. A cosine on pedestal excitation for aperture distribution is used to synthesize the desired directional pattern, which is used to transmit the P1 and P3 pulse for interrogation. Using stationary phase method, the phase function over aperture on the specified aperture amplitude distribution is obtained and the desired pattern to transmit the P2 pulse is synthesized for Interrogation Side Lobe Suppression (ISLS).The antenna and relevant equipment which transmits only the P2 pulse is |
