航管二次雷達(dá)發(fā)射天線方向圖綜合
Transmit antenna pattern synthesis for secondary surveillance radar
-
摘要: 該文介紹航管二次雷達(dá)(SSR)發(fā)射天線方向圖綜合的新方法,這種方法以有源相控陣天線為基礎(chǔ)。利用帶底座的Cosine口徑幅度分布綜合出所需的定向方向圖,輻射用于詢問的P1和P3脈沖。在上述口徑幅度分布基礎(chǔ)上,利用駐相法獲得所需的口徑相位分布以綜合出方位上全向的方向圖,輻射用于詢問旁瓣抑制(ISLS)的P2脈沖。省去了單獨(dú)輻射P2脈沖的天線和相應(yīng)設(shè)備。

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 synthesized 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 saved. -
