PRV-16ML

Mobile height-finder PRV-16ML is intended for measurement of aircraft altitude from target designations provided by interfaced radar or automated control system and bearing of active jammers. By default PRV-16ML distributes data in ASTERIX format. Along with two-dimensional range finders (such as upgraded P-18/P-19 etc.) PRV-16ML forms the back-bone of 3D Radar Complex. System is offered as the upgraded follow-on to the prototype, analogue PRV-16. PRV-16ML can be easily interfaced with surveillance radars and command and control centres such as P-18ML, P-14ML, MARS-L, AMCP "Module", etc. Advanced digital technologies of radar signal processing and solid-state components have allowed to improve performance characteristics and jamming immunity, electromagnetic compatibility, decrease power consumption.

Main functions:

  • acquisition and processing of target designations from interfaced surveillance radars, command and control units;
  • automatic detection and measurement of position (azimuth, slant range, elevation), height calculation;
  • data distribution in ASTERIX format;
  • displaying target designations, air situation and weather formations at technical workstation;
  • manual target designation by operator, automatic height measurement for verbal output
  • automatic detection and bearing (in elevation) of active jammers, data distribution in approved protocol;
  • semi-automatic levelling, automatic topographic positioning based on “Navstar” GPS;
  • automatic technical monitoring and diagnostics.
Detailed information
Principles of upgrade of PRV-16
  • interfacing capability with existing control systems;
  • automatic target detection at specified azimuth, elevation (height) measurement and data distribution to radar sensor (command and control unit);
  • increased mobility due to arranging and accommodating all equipment on a single vehicle, automation of levelling and terrain positioning;
  • fully independent field operation: built-in power generators to back up 380 V, 50 Hz industrial mains;
  • replacement of all outdated equipment with new one not requiring adjustment;
  • minimizing hardware operations in favour of software implemented solutions;
  • built-in diagnostics and technical monitoring system.
Composition of PRV-16ML
  • hardware cabin or truck chassis;
  • antenna waveguide;
  • transmitter;
  • receiver;
  • antenna servo drive control;
  • data processing, displaying and distribution system;
  • power supply system;
  • communication system;
  • levelling system;
  • positioning and orientation system;
  • temperature control system.

PRV-16ML is equipped with advanced semi-automatic levelling system. Levelling accuracy of ± 2’ is achieved.
