Radar (Radio Detection and Ranging) systems use radio waves to detect objects, determine their location, speed, and other characteristics.<br \/>\n1.  Identification of narcotics on passengers at airports or in aircraft: Advanced radar-based scanners, particularly millimeter-wave scanners, are used in airport security for screening passengers. These scanners can detect concealed objects, including weapons and potentially other items like large quantities of narcotics, underneath clothing. So, radar can be used in this activity.<br \/>\n2.  Monitoring of precipitation: Weather radar is a fundamental tool in meteorology used to detect, locate, and track precipitation (rain, snow, hail). It estimates the intensity and type of precipitation and predicts its movement. So, radar is used in this activity.<br \/>\n3.  Tracking the migration of animals: Radar is widely used in biological research, particularly in ornithology and entomology, to study the migration patterns of birds and insects. Weather radar systems often detect large flocks of birds or insect swarms, and specialized biological radars are also used for more detailed tracking. So, radar can be used in this activity.<br \/>\nSince radar can be used in all three listed activities, the correct answer is &#8220;All three&#8221;.<br \/>\n<\/section>\n<section id=\"pyq-key-points\">Radar technology has diverse applications across various fields beyond its traditional use in military surveillance and air traffic control, including weather monitoring, remote sensing, security screening, and ecological studies.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">Different types of radar systems are optimized for specific tasks and targets. For example, Doppler radar is used to measure the velocity of targets like precipitation particles or vehicles, while Synthetic Aperture Radar (SAR) is used for high-resolution imaging of the Earth&#8217;s surface. The versatility of radar technology stems from its ability to penetrate certain materials (like clothing or clouds) and operate day or night regardless of visibility.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Consider the following activities : Identification of narcotics on passengers at airports or in aircraft Monitoring of precipitation Tracking the migration of animals In how many of the above activities can the radars be used ?
