N001 Mech (Russian: Меч, literally Sword) is a Russian (former USSR) all-weather multimode airborne radar developed by the Tikhomirov Scientific Research Institute of Instrument Design (NIIP) for the Su-27 multi-role combat aircraft.
The N001 radar for the Su-27 was designed by Viktor Grishin. Pushing the state of the art for the USSR, the original design, known as Mech, was supposed to draw heavily on technologies developed for the experimental Soyuz radar program led by NPO Istok. It was intended to have a great deal of commonality with the MiG-29's N019 Rubin radar. N001 has a 1.075m antenna diameter twist-cassegrain antenna. A pulse-doppler design operating in the 3 cm band utilising medium and high PRFs for optimum lookdown capability, the N001 has a search range of 80–100 km against a 3m2 m RCS target in a headon engagement, 140 km against a large bomber. It can track a 3m2 target at 65 km. In a pursuit engagement, search range for a 3m2 target falls to just 40 km. Azimuth limits are ±60. Initial units had a MTBF of only 5 hours, but later type is 100 hours; MTBF was eventually brought up to 200 hours. The Su-33 used an updated SUV-33 control system, the N001 radar was largely unchanged but with sea optimised lookdown capability and support for the carrier-based GCI system.
