Echoes of Stealth: Unveiling the World’s Most Elusive LPI Radars

Alright, let’s get informal and dive into the world of Low Probability of Intercept (LPI) radars, which are the ninjas of the radar world. These radars are all about staying under the radar (pun intended) while they do their thing. They’re designed to be super sneaky, making it tough for the bad guys to detect them.

So, here’s a list of some cool LPI radars and their details:

• AN/APG-77: This one’s made by Northrop Grumman and is a key player in the F-22 Raptor. It’s like the radar version of a stealth fighter.
• AN/APG-79: Raytheon’s pride and joy for the F/A-18E/F. It’s got the smarts to keep itself hidden while keeping an eye on the skies.
• AN/APG-81: Another gem from Northrop Grumman, this radar gives the F-35 Lightning II its edge in the sky, staying incognito while gathering intel.
• AN/APG-85: The latest upgrade for the F-35 Lightning II (Block 4) by Northrop Grumman. It’s like giving a ninja a new set of tools to stay even more invisible.
• AN/APQ-181: Originally by Hughes Aircraft (now Raytheon), this radar gives the B-2A Spirit its ghost-like presence in the air.
• AN/APS-147: Made by Telephonics Corporation, this ISAR radar helps the MH60R helicopter play hide and seek over the ocean.
• AN/APG-78: Northrop Grumman’s millimeter-wave fire-control radar (FCR) for the AH-64 Apache. It’s like having eagle eyes that nobody can spot.
• APAR: Thales Nederland’s multifunction 3D radar (MFR) that’s all about being there without being seen.
• LANTIRN: Lockheed Martin’s contribution to the F-16 Fighting Falcon, helping it stay off the enemy’s radar while it does its thing.
• SCOUT: Another sneaky creation by Thales Nederland, using FMCW technology to stay low-key.
• SMART-L: Also by Thales Nederland, this FMCW radar is smart enough to keep itself hidden while scanning the horizon.
• RBS-15 MK3 ASCM: Saab’s FMCW, SAR radar that’s as stealthy as they come.
• SQUIRE: Thales Nederland’s FMCW radar that’s all about being the quiet observer.
• HARD-3D: Ericsson Microwave Systems (now Saab) knows how to make a radar that doesn’t make a peep.
• EAGLE Fire-Control Radar: Another silent watcher from Ericsson Microwave Systems (now Saab).
• POINTER Radar System: Ericsson Microwave Systems (now Saab) created this one to point out targets without making a sound.
• CRM-100: Przemyslowy instytut telekomunikacji’s FMCW radar with 10 switched frequencies, because variety is the spice of life.
• JY-17A: China’s radar with digital phase coding, random FSK, and pulse doppler processing. It’s like a radar with a secret identity.
• PAGE (Portable Air-defence Guard Equipment): This FMCW radar for the ZSU-23–4 is all about guarding the skies on the down-low.
• Uttam AESA Radar: Electronics and Radar Development Establishment, DRDO, India’s solid-state GaAs-based AESA radar for the HAL Tejas. It’s India’s way of saying, “You can’t see me!”
• CAPTOR-E: A collaboration between Hensoldt, BAE Systems, Leonardo S.p.A., Thales Group, and Airbus Defence and Space for the Eurofighter Typhoon. It’s the radar that plays it cool while keeping an eye on everything.

And there you have it, a rundown of some of the most elusive radars out there. These radars are all about being heard and not seen, making them the ultimate players in the game of aerial hide and seek. 🛩️🚀
