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.
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。

This paper investigates the secondary pattern performance for the small electrical size subreflector and large lateral-feed displacement.
