Abstract :
In this paper, an approach to the synthesis of FHA for limited field of view in one plane is developed. From the considered examples, it can be seen that in the case of limited field of view, the FHA allows us to appreciably reduce the feed array size and the controlled element number as compared with the HA with parabolic cylindrical reflector. The considered approach to FHA synthesis can be generalized in several directions: (a) offset system with no blockage, (b) dual-reflector system with ordinary (commercial) main parabolic reflector and a small focuser-subreflector, (c) HA with a divergent reflector for extended field of view, etc
