The antenna sidelobe level requirements are different for different PRFs because the ranges within which the sidelobeclutter competes with the target signal are different.
对于不同的重复频率，与目标相对抗的杂波距离是不同的，因而对天线旁瓣电平的要求也不一样。

A new way is proposed to evaluate the sidelobe requirement of an AEW radar based on analysing the clutter intensity.
