Electronic Scanning Ground Surveillance Radar

SW-R6E is a reconnaissance and monitoring system with multi-target display and TWS&TAS functions, since the System is adjacent to enemy and works in complicated EM environment, it has LPI and anti-jamming functions. The targets(usually crowds and vehicles) can be classified roughly, i.e. the type (including individual soldier, a crowd of soldiers, individual vehicle, a crowd of vehicles, aircraft) can be identified based on echo strength and target moving speed, and the system monitors the activities of tracked targets (specially individual solider, moving soldier crowd, moving vehicles, boat/ship, low-altitude penetration armed helicopter), including the location and track, and conducts target identification and automatic warning.

SW-R6E conducts target detection, target display, track record and access, digital map display, manual control commands, coordinates conversion, intelligence report, storage and output etc.


System Objectives

SW-R6E Ground Surveillance Radar is used to search, monitor, track and warn against moving targets such as person, troops, vehicles, boat/ship and low-altitude UAV etc. in warning area. It can detect, identify the target type & threat level and give warning automatically. Typical applications are as follows:

  • Battlefield reconnaissance: used by armored forces and maneuvering infantry company for battlefield reconnaissance and situation display.
  • Anti-air target: locate and track the low-flying aircrafts, such as hostile helicopter and UAV.
  • Border surveillance: monitor enemy force rally and vehicle maneuvering, monitor and warn against sneak attack of small forces.
  • Special-police reconnaissance: used by special police to search and warn criminals in special situations, such as smuggling etc.


  • Compact size and light weight. The SW-R6E is easy for the soldiers to carry and use in the complex and adverse terrain areas such as frontier, mountain, plateau, seaside, island and reef etc. The equipment can also be mounted in the vehicle.
  • Advanced techniques: AESA Pulse Doppler radar system, fully electronic scanning in azimuth, the scan angle more than 90°, pointing control of high-accuracy rapid wave-beam, complete solid state, full-coherent, frequency agility and pulse compression technique, capable to detect very low speed moving targets and achieve extra high specifications.
  • Powerful anti-jamming capability by adopting linear FM pulse compression technique, constant false alarm rate (CFAR), frequency agility, MTI and MTD techniques.
  • Adopt advanced digital techniques, modular design, standardized design, redundancy design, strict components selection and lots of integrated circuits with high integral reliability.
  • Easy-to-operate: high automaticity, supporting unattended duty and remote-controlled expansion interface available.
  • Extra high capacity battery and low power consumption to achieve very long operational time in field.
  • TWS and TAS functions available.
  • High class ILS: low operation cost, low maintenance cost and radar LCC.
  • Various digital maps available.

The block diagram of SW-R6E is shown as the following Fig. 3.

Electro-optical Sensing Subsystem (Optional)

This electro-optical sensing subsystem collaborates with SW-R6E. The system transfers detected target location data to EO sensor, and the sensor subsystem controls the rotator and adjusts the focus of EO devices, so as to acquire target images and accurate range data, even target video if necessary.

Vehicle-Carried Operation

It is easy for SW-R6E to be mounted in the container of light-duty vehicle after simple retrofit, and the container could be equipped with an enclosed cover, besides, the front seat could be retrofitted as operation cabinet. In the container, a hydraulic lifting mast can be installed in container, and the radar will be mounted on the mast. Under the non operation status, the hydraulic mast is retracted. During operating, open the container and lift the radar, adjust the height of the mast and pointing of radar.

Under the vehicle-carried mode, radar could be powered by Li-ion battery, or onboard DC24V power supply.
