    The primary surveillance radar is subject to the radar equation that says signal strength drops off as the fourth power of distance to the target. Objects detected using the PSR are known as primary targets. The second system is the secondary surveillance radar, or SSR, which depends on a cooperating transponder installed on the aircraft being ...
