Mobile-based altimeter PRV-13 is designated:
- to determine the flight level of air objects in conjugation of the ACS (automated control system) objects of various types;
- to work in the ranging mode for low-flying targets as part of automated radar stations;
- to determine the azimuth, range and altitude of air targets offline.
The structure of the mobile radio altimeter PRV-13:
- trailer V1, V2, V3;
- containers and frameworks

Modernized radio altimeter provides:
- the receiving and displaying of two-coordinate radar with analog or digital output;
- the automatic detection of air targets with the measurement of height, azimuth, slant range of external target designation;
- the increased sensitivity of the receiving channels due to the replacement of amplifiers based on running wave lamp amplifier with low-noise transistor amplifiers of type USVT-3;
- implementation of digital processing algorithms and information displaying methods, replacement of analog equipment of processing signals to the digital;
- increasing reliability and reducing power consumption by reducing the quantitative composition of the equipment and replacement of electronic devices (up to 600 pcs. 60 types) with semiconductor devices and modules;
- improving the quality of displaying the radar situation of on the color LCD display;
- electronic registration of radar data, the results of monitoring the technical status and diagnosing the equipment, documenting combat performance of the operator;
- the topographic binding of the altimeter location using the receiver of navigation systems GLONASS/GPS and determining the current time;
- increasing the convenience and comfort of staff operation due to the automatic air conditioning, heating and fire alarm systems;
- automatic transfer of information about the coordinates of air objects for remote consumers.
