contract with Bharat Electronic Limited (BEL) to procure Improved Low Level Light Weight Radar (LLLR-I) at a cost of approximately \u20b9 770 Cr.\u00a0<\/span><\/p>\n<h2><b>About Low Level Light Weight Radar \u00a0 <\/b><\/h2>\n<ul>\n<li><span style=\"font-weight: 400;\">It is a <\/span><b>next-generation<\/b><span style=\"font-weight: 400;\">, <\/span><b>multi-mission radar<\/b><span style=\"font-weight: 400;\"> designed to detect and track different types of aerial targets.<\/span><\/li>\n<li><b>Design<\/b>\n<ul>\n<li><span style=\"font-weight: 400;\">The radar&#8217;s <\/span><b>four antenna panels<\/b><span style=\"font-weight: 400;\"> are mounted on <\/span><b>tripods and are passively cooled<\/b><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">This system does not require mechanical movement or liquid cooling.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">It features a <\/span><b>built-in self-test function<\/b><span style=\"font-weight: 400;\"> to help identify technical issues.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">It operates via a <\/span><b>control and display unit (CDU)<\/b><span style=\"font-weight: 400;\"> which allows operators to remotely control radar modes and view the air situation through a human-machine interface.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2><b>Features of Low Level Light Weight Radar<\/b><\/h2>\n<ul>\n<li><b>Coverage<\/b><span style=\"font-weight: 400;\">: It uses four <\/span><b>fixed phased-array antenna panels<\/b><span style=\"font-weight: 400;\"> to provide complete <\/span><b>360-degree surveillance.<\/b><\/li>\n<li><b>Technology<\/b>\n<ul>\n<li><b>Active Electronically Scanned Array (AESA) technology<\/b><span style=\"font-weight: 400;\">: The system uses <\/span><b>Active Electronically Scanned Array (AESA) technology<\/b><span style=\"font-weight: 400;\">, which allows it to electronically direct radar beams rather than physically move the antenna.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">It also incorporates <\/span><b>Gallium Nitride (GaN) amplifiers<\/b><span style=\"font-weight: 400;\"> and <\/span><b>digital beamforming technology<\/b><span style=\"font-weight: 400;\"> to improve radar performance.<\/span><\/li>\n<\/ul>\n<\/li>\n<li><b>Three-Dimensional Processing: <\/b><span style=\"font-weight: 400;\">It uses <\/span><b>advanced three-dimensional processing capabilities<\/b><span style=\"font-weight: 400;\"> to distinguish targets from unwanted radar returns and reduce the effects of multipath interference.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">It is crucial for detecting <\/span><b>small drones and other low-RCS<\/b><span style=\"font-weight: 400;\"> (low radar cross-section) targets.<\/span><\/li>\n<li aria-level=\"1\"><b>Tracking<\/b>\n<ul>\n<li><span style=\"font-weight: 400;\">It can <\/span><b>automatically track targets<\/b><span style=\"font-weight: 400;\"> while <\/span><b>continuing to scan the surrounding airspace <\/b><span style=\"font-weight: 400;\">through its <\/span><b>Track While Scan capability.<\/b><\/li>\n<li><span style=\"font-weight: 400;\">It can also <\/span><b>prioritise detected aerial targets<\/b><span style=\"font-weight: 400;\">, allowing the Army to identify threats that require attention.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Its <\/span><b>monopulse tracking technique<\/b><span style=\"font-weight: 400;\"> provides accurate target tracking in elevation.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">It has the ability to provide target information to <\/span><b>weapon systems through wired or wireless communication links.<\/b><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Electronic Counter-countermeasure (ECCM) Capabilities:<\/b><span style=\"font-weight: 400;\"> It also incorporates <\/span><b>electronic counter-countermeasure (ECCM) capabilities<\/b><span style=\"font-weight: 400;\">, designed to help maintain radar performance in the presence of electronic interference.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Adoptability:<\/b><span style=\"font-weight: 400;\"> It is light weight operable
