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). 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。
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. 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。
