Millimeter-wave radar

Movement detection radar systems are currently in active use both in combat operations and for “public security” applications such as global war on terrorism or crime control. Such radars are designed to detect force and AFV [armored fighting vehicle] movements, generate target data for fire control assets, secure national borders or restricted access areas, and to provide friend-or-foe identification. The Open Joint-Stock Holding Company Ukrspetstechnika represents Ukraine on the international market niche for moving target detection radars. The OJSHC Ukrspetstechnika, having analyzed the advantages and disadvantages of pulse and continuous wave centimeter/millimeter-wave radar technologies, started its advancement on the target detection radar market by developing the movement detection short-range radar systems currently known as LIS and BARSUK. The latter radar design employs continuous-wave millimeter-wave radiation mode, enabling all the advantages of the continuous-wave code modulation and millimeter-wave radiation modes to be implemented to the maximum possible effect. At the start of 2004, BARSUK successfully passed through government trials and was accepted as standard issue for the Ukrainian Armed Forces. The launch customer for movement detection millimeterwave radar systems BARSUK and LIS was Ukraine’s Border Security Authority. Movement detection radars of this kind are indispensable in operations involving threats such as terrorists, intruders or saboteurs. The radar is based on the continuous-wave code modulation which provides advantages such as improved target range measuring capability and enhanced resistance to natural interference, active jamming attempts or unintended interference.

Millimeter-wave radar technologies enjoy a number of significant advantages over other radar types, and are therefore more suitable for use as threat detectors.

These advantages are as follows:

  • Reduced weight and bulk, allowing the radar to be used for various applications, including mobile and man-portable weapons systems;
  • Because the system uses millimeter-wave frequency band, it does not pose any health hazards to the operator, and it is almost insensitive to random noise or electronic countermeasure, neither does it generate electromagnetic interference with other systems on site;
  • Enhanced countermeasures resistance;
  • Enhanced signal processing performance using signal coding and phase modulation;
  • Improved target location performance capabilities;
  • Capability to operate in reduced visibility conditions (snowfall, high smoke content, fog, rainfall etc);
  • Enhanced target tracking capabilities;
  • Low mean output power, meaning that the radar is very hard to detect by intercept receivers;
  • Improved detection performance capability for small-size surface targets.

Ukrspetstechnika offers to domestic and export customers a comprehensive range of movement detection radar systems tailored to specific operating environments and customer requirements, with emphasis placed on performance capabilities such as the detection of stationary and moving targets; target classification and friend-or-foe identification; target discrimination and target tracking in intense electromagnetic environments. The Ukrspetstechnika’s radar systems provide a broad variety of capabilities, including automatic target tracking and guidance; discrimination of most hazardous threats; computer-assisted matching of displayed data with terrain; the possibility to process, display and record the radar output data on a laptop computer.

Barsuk family of man-portable movement detection short-range radar systems

BARSUK radars are portable man pack systems designed for monitoring, automatically detecting and providing the warning about moving persons, vehicles or surface vessels inside or near restricted areas. Targets are classified by warning signals specific to each target type (persons, groups of persons, vehicles or animals). Man-portable systems of this type are indispensable in patrol and policing operations or during pursuing intruders in reduced/zero visibility environments.

The 112L1 BARSUK (baseline configuration) – man-portable threat detecting radar designed to detect moving persons, vehicles or surface vessels.

The 112L2 BARSUK-T – portable tripod-mounted movement detection radar system which off ers the same capabilities as the baseline configuration, but provides a wider scan sector (120 degrees), along with an extended operating range.

The 112L3 BARSUK-PG – a compact radar system mounted on the grenade launcher’s carriage or the machine-gun’s mount and designed to support fire control in multiple target environments, particularly under zero visibility conditions. Targets are classified by warning signals specific to each target type (persons, groups of persons, vehicles or obstacles). The system employs a micro strip solid-state transmitter-receiver.

Lis family of short-range target detection radar systems

111L1 LIS (baseline configuration) is a vehicle carried moving target detection system providing a scan sector of 120 degrees in azimuth. Its target range includes human beings, surface vessels and low-flying helicopters

111L2 LIS-M is a moving target detection all-round-looking radar system provided in a man-portable tripod-mounted configuration. It is designed for the detection of human beings, vehicles, surface vessels and low-flying helicopters, and it is also suitable for adjusting artillery fi re at distances up to 12 kilometers. The LIS provides automatic target tracking capabilities, and can operate in all weathers, in daylight environments and at night time. Target data (image, range, velocity) is displayed on an LCD screen monitor. Configuration of the system enables it to be mounted on vehicles of all types. 11L2 Mangust Man-portable movement detection radar system

Mangust Man-portable movement detection radar system

The Mangust man-portable mobile ground target detection radar system is suitable for military and homeland security applications, including battlefield surveillance and scanning national land/maritime borders for security. The entire system is man-portable in two 20-kg loads, and it requires a two-man crew to operate and maintain. Time into and out of action does not exceed five minutes. The radar is mounted on a 1.5-m-high telescopic tripod. Control is performed using a PC-based operator console which can be up to 50 m away from the tripod-mounted radar unit. The radar employs continuous-wave millimeter-wave radiation mode to detect and locate moving targets and to display target data on operator display unit. Target detection and target position location functions are performed by a processor built into the operator console. The radar can be programmed to provide full spherical coverage or coverage of a predetermined sector of interest. Target data is displayed in the form of a label with an assigned target reference number, and includes parameters such as target range, azimuth and identification points. Provisions are made for pre-determining blanking zones or scanning sectors of special interest. The technology uses a solid-state transistorized transmitter offering a low mean power output of 0.01…1.0 W in order
