Based on the principles that lateral offset-focus feed makes the antenna pattern deflect an angle, the multi-beam antenna can be used in passive imaging system.

本文首先分析了焦平面阵列馈源横向偏焦产生多波束的原理，并采用面电流法对偏焦抛物面天线方向图进行了编程计算。

More specifically, the spray bar includes one or more manifolds connected to dedicated feed lines each having a spray head, resulting in improved lateral spray distribution.

更具体地，喷杆包括与各自具有喷头的专用输送管路相连的一个或多个歧管，从而改进横向喷流分布。
