Picture

Figure 22. This aircraft warning radar van is parked in a village area. The tall trees provide dark shadows during the day that help to mask its presence. Note the electronics van is barely visable, however the yagi-type antenna can be seen extending over the tops of the adjacent trees. The photo signature that led interpreters to this site is the shadow of the radar antenna. Can you see it on the ground?
