Peace Time / War Time Applications of Radar. Radar has been employed on the ground, in the air, on the sea and in the space. Ground based radars are applied chiefly to the detection and tracking of a/c or space targets. Ship borne radars are used for navigation aid and safety device to locate buoys shorelines and other ships and also observing the aircrafts. Airborne radar may be used to detect targets and ships or land targets. Space radar has assisted in the guidance of spacecraft and remote sensing of the land and sea. Some of the important applications of radar are described in brief in the following paragraphs:
(a) Air Traffic Control. Radar is employed throughout the world for the purpose of safety controlling of aircraft en route and in the vicinity of airport. Radar has been used in GCA (Ground Controlled Approach) to guide the a/c for safe landing in bad weather conditions and in nighttime.
(b) Aircraft Navigation. The weather avoidance radar used in the a/c to outline the regions of charged clouds. Airborne radars are also used for terrain avoidance and terrain following. Ground mapping radars with moderately high resolution are used for a/c navigation purposes.
(c) Ship Safety. Radars used in ships for enhancing the safety of ship travel by warnings of potential coalition with the others ships and for detecting navigation buoys especially in poor visibility. Shore based radars is also used for surveillance of harbors as an aid to navigation.
(d) Space. Space vehicles have used radars for docking and for landing on the moon. Some of the largest ground based radars have the capability of detecting and tracking of satellites. Satellite borne radars have also been used for remote sensing as mentioned below.
(e) Remote Sensing. Remote sensing radars are concerned with earth resources, which include the measurement and mapping of sea conditions water resources, ice cover, agriculture & forestry conditions, geological formation and environmental pollution.
(f) Law Enforcement. Radars used to measure the speed of automobile traffic on highways by Transport Dept and Traffic Police.
(g) Military. Military applications are detection, identification and interception of airborne targets Air Traffic Control, Navigation, tracking, weaponry guidance, AWACS, UAV guidance etc.
