Why is AN/APG-81 AESA Radar the most powerful airborne radar?

The full form of Radar is radio detection and ranging. It is a detection system that uses radio waves to determine the distance (ranging), angle, and radial velocity of objects relative to the site. An airborne radar system is designed to detect aircraft, ships, and vehicles at long ranges and perform control and command of the battlespace in an air engagement by directing fighter and attack aircraft strikes. The most powerful airborne radar is AN/APG-81 AESA Radar. Here are the reasons why-

The AN/APG-81 is an active electronically scanned array (AESA) radar system designed by Northrop Grumman Electronic Systems for the Lockheed Martin F-35 Lightning II.

The Northrop Grumman AN/APG-81 active electronically scanned array or AESA radar centerpiece at f-35 lethality. It provides unmatched capabilities for air-to-air, air-to-surface, stealth, and electronic warfare operations. At the heart of the AESA is miniature transmit and receive or TR modules. The APG-81 AESA radar has over 1,000 TR sights and includes an advanced receiver and exciter that are capable of extreme waveform agility and are mounted behind the AESA with no moving parts. The numerous TR modules are electronically steered together to provide nearly instantaneous beam repositioning. There was an actual flight test where 23 targets within 100 miles, 19 targets are detected and tracked in under three seconds and all 23 targets are detected and tracked in under nine seconds.

The APG-81 AESA radar supports simultaneous air-to-air and air-to-ground operations and makes huge high-resolution SAR maps at long ranges with a single look. The APG-81 automatic target cueing rapidly locates targets and reduces pilot workload. The pilot can simply zoom in on an area of interest to expand the detail with no new map required.


All this specification makes AN/APG-81 AESA radar the most powerful airborne radar.

10 Practical and Enlightening Quotes from THINKING FAST AND SLOW by Daniel Kahneman by Muinuddin Bashar

Image
  In 2002, Daniel Kahneman won the Nobel in economic science. What made this unusual is that Kahneman is a psychologist. Specifically, he is one-half of a pair of psychologists who, beginning in the early 1970s, set out to dismantle an entity long dear to economic theorists: that arch-rational decision maker known as Homo economicus. The other half of the dismantling duo, Amos Tversky, died in 1996 at the age of 59. Had Tversky lived, he would certainly have shared the Nobel with Kahneman, his longtime collaborator and dear friend. In his mega bestseller, Thinking, Fast and Slow , Daniel Kahneman , world-famous psychologist and winner of the Nobel Prize in Economics, takes us on a groundbreaking tour of the mind and explains the two systems that drive the way we think. The first system is fast, intuitive, and emotional ; the second system is slower, more deliberative, and more logical . The impact of overconfidence on corporate strategies, the difficulties of predicting what wi...
