This is a side view of our red "chicken's eye." The entire 256 square mile area, from the ground up, is assigned preferred coverage from radar B (Clearfield in our case), which is nearly 100 miles away. Assigning radar B as preferred over radar A's location takes care of the cone-of-silence problem, as aircraft 4 is detected and processed for display. But look what happens to the low-altitude aircraft. In this example, aircraft 2 & 3 are solidly detected by radar A, but radar A's data is not used. The data made it to the facility, but by the process of selective rejection, this data goes unused, as radar B is assigned preferred. Radar B just barely sees aircraft 3, but it definitely doesn't see aircraft 2.
What can happen when sort boxes are adapted in this manner?
