"Radar.bas" is a sort of simulation of an old-fashioned analog radar display where "blip" echos are refreshed each time the beam sweeps around and gradually fade as the phosphor dims exponentially until the next sweep.
Targets are created with random locations, velocities, and transponder ID's. As they drift out of range, new targets come into view.
The table to the right shows target ID's, ranges (in screen units), and bearings from the screen center. Bearings in degrees are different from the usual mathematical conventions: North is zero degrees and bearing increases clockwise.
By clicking 'T' (target), 'R' (range), or 'B' (bearing) you can sort the table entries by that column. Click the same letter twice or more in a row to change the sorting direction.
Click 'Q' to quit the simulation
