Which radar type works alongside airport surveillance radar (ASR) in the AN/MPN-14K LCC?

The reason precision approach radar (PAR) is the correct answer is that it is specifically designed to work alongside airport surveillance radar (ASR) to provide highly accurate guidance to pilots during the approach phase of landing. PAR offers precise lateral and vertical guidance by measuring the aircraft's position relative to the runway, which complements the broader capabilities of ASR that primarily focuses on tracking aircraft within a specified area of airspace.

Using PAR in conjunction with ASR enhances the overall efficiency and safety of aircraft landings, particularly in low visibility conditions. ASR provides situational awareness regarding air traffic, while PAR gives crucial guidance to pilots to ensure that they safely intercept the glide path and land on the runway.

In contrast, the other types of radar mentioned serve different operational purposes. Moving target indicator (MTI) radar is primarily used to detect and track moving targets in cluttered environments, which is not its main function in airport operations. Ground controlled approach (GCA) is more of a procedural approach that involves ground controllers guiding aircraft, but it does not provide the same precise radar-based approach aids as PAR. Air traffic control radar (ATCR), while important for managing air traffic, does not focus on the precision approach needed during landing as PAR does. Hence
