[ARC5] APN-1 radioaltimeter

[Fuqua, Bill L]

  I have been looking into the APN-1 radio altimeter design lately. It is very interesting, I have known the fundemental theory behind it since I was a teenager but I have realized that there are some subtle details that I had never though of. However, I would like a higher resolution schematic than I can find on internet  and component values to investigate further.
