It features a pulse repetition frequency of 400, 800, or 1,400 Hz, a pulsewidth ranging from 0.6 to 4.0 µs, and an instrumented range of 320 km. The Kontur-10C version utilizes decentralized transceiver modules separate from the antenna, while the Kontur-10M is a compact design, and the Kontur-10SV includes a specialized mode for detecting wind shear.
