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 logarithmic-periodic 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 1000 m.
