I don't know if it could be useful or just pertinent, but I modeled one of the features of the Intruder's Terrain avoidance radar. It displays the ground elevations relative to the aircraft's datum line. the radar shadow is also computed. Have a look at the A-6E the display is just under the video Attitude Indicator.
