Primary radar range finding is based on measuring the time between a transmitted pulse in the UHF or SHF band and the reception of the reflected pulse from the target. Ground radar installations have widely varying ranges depending on their purpose and the design and operating parameters, such as frequency, pulse timing sequence, and rate of rotation, are determined by the range required. Airborne Weather Radar (AWR) has become standard equipment on commercial transport aircraft and has led to a significant improvement in safety and passenger comfort as it allows pilots to go around or over storms. The secondary surveillance radar (SSR) system is used to provide additional information about traffic that cannot be obtained by primary radar alone. The radio altimeter provides an accurate measurement of the height of the aircraft above the ground upto a maximum of 5000 ft, though for most radio altimeters used on commercial aircraft the limit is 2500 ft.
