Designed for command and control, the AN/UPX-44, -505 and -506 monopulse and AIMS Certified, All-Mode IFF interrogators enable air traffic controllers and air defenders to identify military and civilian aircraft, verify forces as friendly and determine their bearing and range. Our interrogators are deployed in fixed- and rotary-wing aircraft, shipboard, ground-based and mobile radar installation sites. All three systems comply with U.S. and international specifications that define interrogator modes, performance, control, reporting and interface. To easily introduce performance upgrades, the system uses common module hardware and software for the detection, interrogation, identification tracking and data extraction of small targets in severe environments.
