And here is my question. If there is no need to mechanicaly steer the antenna why is there scanning time when radar scanns from left to right (horizontaly) and from 1st to 4th bar (verticaly). If radar is electronicaly scanned shouldn't this scann be done is a fraction of a second, much like a ccd camera scanns across all pixels in a ccd element?
even if there is a problem of signal interferance and we can only have one cell active at present time this still doesn't explain the F18s full scanning time of more than 10 sec. Radio signal is fast and even if we shoot at 100 km distante target we get the echo instantly or in about half a milisecond. So even if there's a 1000 cells ia a radar array and if we get a window of 1 milisec for each cell we would scann acros the entire ray in 1 second.
