In radar applications, single-pulse antennas can be used with array antennas, as well as reflective surfaces and single-pulse feeds. If a single-pulse feed is used, the feed typically uses multiple (4) or single-port multimode speakers.
The working principle of single pulse technology in the plane (pitch surface).
Radar antenna when a laterally-focused horn is placed near the parabolic focus, the antenna will produce lobes that deviate from the antenna axis. The beam offset angle sθ is proportional to the defocus distance x.
