Radar System Definition Purpose Components Advantages Disadvantages ASR Airport Surveillance Radar: Short-range radar system with range up to 60-nautical miles. -Used by civilian and military airports. -Used by approach and departure controllers. -Used to detect and display aircraft within the terminal area. - 2D radar. Paired with a secondary surveillance radar (SSR) that works with the ASR. -Uses continuously rotating antenna. -SSR has second radar beacon antenna attached to the primary antenna -Can aid instrument approaches. -Can operate at different frequencies if necessary -Does not provide altitude data on its own (must be paired with SSR) -Very short range -Limited to line-of- sight ARSR Air Route Surveillance Radar: Long-range, enroute radar systems located hundreds of miles from ARTCC. -Used by ARTCC -Used to provide separation services to aircraft. -Detects aircraft outside of terminal areas (in the enroute phase of flight). -Used to monitor coastlines and borders. -Three- dimensional -Unattended, remote monitoring. - Signals can be sent to multiple facilities -Can display weather in addition to flight services. -Can be used to monitor large areas. -Can be repaired while in operation

ASDE Airport Surface Detection Equipment: Short-range system located at airports to determine location of aircraft and vehicles on or near the ground. -Used by Control Towers. -Locate and display aircraft and vehicles on the ground in low-visibility conditions. -Locate and display aircraft near the ground (on final). -Used at high- activity airports where low-visibility is common. -Helps reduce runway incursions. -Surface surveillance radar. -Multilateration sensors. -Airport surveillance radars (ASRs) -ADS-B sensors -Works within 200 feet of ground -ADS-B allows radar surveillance in areas with challenging terrain. -Can detect aircraft without ADS-B or with malfunctioning transponders. -High resolution and clutter-free information for controllers. -Automatically combines info from all sensors, which increases accuracy and safety. -High failure rates that leave controllers with blank screens. -Contains many components that can malfunction. Write a 150-word paragraph referring to Module 6 PSA Flight 182 accident. The PSA Flight 182 was an accident that could have been avoided, had the pilots and ATC been more mindful of what was going on. The pilots would have been communicating with TRACON (approach and departure controllers), who would have been using Airport Surveillance Radar (ASR). This radar is designed to monitor an area within 60 nautical miles, and both planes were within this range. The controller should have been using this radar to monitor where the planes were flying and how close they were to each other. The controller then should have informed the pilots that their paths were extremely close or given them specific instructions to separate them from each other. The controller should have recognized that the Cessna pilot had deviated from their heading. The lack of attention to these details is what resulted in the two aircraft colliding mid-air, but easily could have been avoided with more attention. Write a 250-word paragraph summarizing how radar systems will evolve in the future. Every aspect of aviation is improving constantly, and radar systems are no exception. Current radar systems are two and three- dimensional systems, but there are plans to move toward four-dimensional systems by the year 2030. 4D radar would improve velocity resolution, robustness to interference, object classification and tracking, range resolution, and more. The FAA also plans to divest in some current radar systems due to overlapping surveillance coverage to save on costs and optimize the systems.
