RK-11

The RK-11 is a Synthetic Aperture Radar (SAR) designed for high-resolution, two-dimensional ground imaging. Operating in the Ku band (IEEE designation) or J band (NATO designation) at a frequency of 15.36 GHz, it offers an instrumented range of 2 km and a range resolution of 0.25 m. This versatile system can be mounted on various light unmanned rotorcraft, fixed-wing aircraft, and other flight platforms, providing all-day, all-weather, quasi-real-time high-resolution remote sensing and telemetry. The complete system is cylindrical, measuring 130 mm in diameter and 220 mm in length, weighing 1.5 kg, and requiring a 50-watt power supply.
