Malachit

Malachite (Cyrillic: РЛС «Малахит») is a VHF-band surveillance radar developed by a Ukrainian company using the robust Russian mechanical parts from the technologically obsolete P-18. The frequency range is attractive, as the usual stealth measures do not work in this range. The so-called stealth bombers are sometimes even better to detect than conventional airplanes. From the original radar, only the Yagi-antennas with the wideband feeding are still preserved, which suggests the use of the approximately same frequency range from 155 to 170 MHz.

The radar is equipped with semiconductor components and uses a phase-modulated intrapulse modulation. Due to the coded transmit signals, active noise interference is ineffective as long as it does not lead the receiver into overdrive.

The radar is fitted with a digital radar signal processor that can track up to 250 targets automatically. Like its predecessor, the radar can be coupled with other radars, for example with the PRV-16 height finder and Russian interrogators. Malachite can be remote-controlled from a distance of up to 1 000 m.
