Planar array radar
Operation
A fixed delay is established between horizontal arrays in the elevation plane. As the frequency is changed, the phase front across the aperture tends to tilt, with the result that the beam is moved in elevation. The differing frequencies cause each successive beam to be elevated slightly more than previous beams. A 27.5-degree elevation is scanned by the radar.
Advantages
- Each beam group has full transmitter peak power, full antenna gain and full antenna sidelobe performance.
- The use of frequency changes allows economical, simple and reliable inertialess elevation scanning.

gollark: Also targeted advertising through entity sensors.
gollark: Fun idea: for the more centralized advertising systems people seem to be considering, instead of buying slots for a certain time, run an automated auction every time each ad display or whatever displays a different thing to decide what to display.
gollark: I've been doing yet more ~~debugging~~ deintendedfeatureing.
gollark: Anything interesting going on ingame?
