J/APG-2

1. 본문

The J/APG-2 is an advanced Active Electronically Scanned Array (AESA) radar system developed by Mitsubishi Electric for Japan's F-2 fighter jets. It is an upgraded version of the J/APG-1, which was notable for being the first series production AESA radar introduced on an in-service military aircraft.

Here's a breakdown of its key features and capabilities:

• Technology: The J/APG-2 radar utilizes gallium-nitride (GaN) technology in its transmit/receive modules.
• Enhanced Performance: This upgrade provides a significant boost in beam power (reportedly by 300%) and increases the detection range, stated to be 75 miles (120 km).
• Improved Capabilities: It has built-in electronic warfare (EW) and missile tracking features.
• Compatibility: It's designed to be compatible with the Mitsubishi AAM-4B air-to-air missile, enabling long-range target detection for the missile.
• Faster processing: The radar includes a new, faster, and more reliable signal processor.
• Stealth Focus: An upgraded version, tested in 2019, has a stronger focus on tracking and targeting stealth aircraft. This upgraded version works in conjunction with the IRST (Infrared Search and Track) sensor.
