Sonar busted again

Quickly bringing the sonar airframe up to a minimal flying condition showed all those extra clockcycles & radios still didn't get sonar over the hill. It may have been marginally better, but already getting a Marcy aircraft to fly indoors showed it took absolutely glitch free, razor accurate altitude data. The problem with ground based sonar is not the range or the directionality, but it glitches.

Horizontal data seems good enough. There's definitely a future for it if it's combined with a straight down sonar for altitude. Straight down sonar would work, if an amplifier was put on the flight board. The processing would have to be done in software, since hardware to detect reflected sonar on 1 sensor has been patented out of existence. It may be patented in software, too.
