3D C/D band air surveillance radar on a HMV

A new mobile radar system based on BEL 3D C/D Band Air Surveillance Radar which was revealed during Defence Expo 2018.

It is a Multi-Function Active Phased Array Radar with Solid state Transceiver for Land and Naval applications.

The Radar provides 3 dimensional target data along with Doppler data.

The Radar employs multi-beam in elevation, mono pulse in azimuth, Digital Pulse compression, Pulse Doppler and many Advanced and contemporary Technologies, with very elegant and modular architecture.

These technologies enable detection of very low RCS targets from complex land clutter and jamming environment.

Current status : development finished

Battery Surveillance Radar ( BSR )

It is a C band GaN tech based state of the art active phased array radar which uses advanced signal processing and data processing algorithms to detect and track fixed wing aircrafts including UAVs as well as rotary wing aircrafts including hovering helicopters in intense EW environment.

The Radar uses advanced platform motion compensation and electronic stabilization algorithms along with high accuracy motion sensors. It can search, track and acquire targets on the move .

Range is 120 km for 2 m2.
Altitude is 30 m to 6 km.

The radar and IFF ( interrogator friend or foe ) system is mounted on a 8x8 HMV with integrated on board power and cooling system and are capable of operating on the move in plains, deserts and semi deserts.

What is unique about this radar system is that the radar panels are flush with the vehicle body. This makes the radar system unique among its contemporaries. From a distance it will look like just a ordinary truck.

One can see 2 radars and 2 IFF antennas one each on the front and rear end of the vehicle and 2 radars and 2 IFF antennas at the either of the HMV. This also provides for full 360 degree coverage.

The radar will be installed and integrated at high altitudes deployment sites. It is capable of being sited up to an altitude of 3000m Above Mean Sea Level. It can withstand severe environment conditions and will also be integrated to the IACCS Network of IAF.

Sanction was given for initial 12 HPR radars in order to develop the same for providing long range, medium and high altitude cover while detecting and tracking low and high speed airborne targets.

Technologically superior, the radars will have the capability to scan 360 degrees without mechanical rotation of antenna and will operate on 24X7 basis with minimal maintenance requirements.

SWATHI Weapon Locating Radar (WLR)

Weapon Locating Radar (WLR) is an electronically scanned phased array radar. The radar automatically locates hostile artillery, mortars and rocket launchers and tracks friendly fire to locate the impact point of friendly artillery fire to issue necessary corrections.

It is derived from the Rajendra Radar (which is the fire control radar for the Akash missile system).

The radar is designed to detect projectiles with small cross section across the battle space horizon, and has the capability to handle simultaneous fire from weapons deployed at multiple locations.

On detecting an incoming hostile round, the radar automatically acquires and classifies the threat and initiates a track sequence while it continues to search for new targets. Algorithms for trajectory computations use environmental factors, along with trajectory and track data, for estimating both launch and impact points to the desired accuracy. The fence concept of beam positioning, and grazing the radar air space, makes it hard for hostile projectiles without detection.

The computed launch point can be reported by the radar operator to the friendly artillery to direct counter-battery fire towards enemy artillery. Tracking of the target is achieved with mono-pulse signals and the in built pulse compression features improve the radar’s low probability of interception (LPI). Its processors perform real-time signal processing on the acquired data. An adaptive algorithm based on modified version of the Runge-Kutta method and incorporation of constant false alarm rate (CFAR) techniques aid in the accuracy of target detection. An operator can select the suitable CFAR technique for maximising accuracy of track/information. The data is processed on the state-of-the-art programmable digital signal processor using modified extended Kalman filters (one with size six states and another with seven states). Moving target indication (MTI) aids to improve the clutter rejection performance of the radar.

The radar uses advanced signal processing techniques for detection and tracking projectiles in the presence of ground, weather clutter and other forms of interference in EW scenario. Algorithms for trajectory computation take environmental parameters into consideration while estimating both launch and impact points for desired accuracy.

The radar is designed for high mobility, quick deployment and decamp. The physical profile consists of radar shelter, antenna and cooling mechanisms which are placed on a slewable platform.

System is designed to survive physical rigours of battlefield and soft hostile electronic warfare.

It has 2 versions

1. Weapon Locating Radar MK1 for plains

Radar vehicle

Power source cum BITE vehicle

2. Weapon Locating Radar MK2 for mountains

Radar vehicle

Command cum power source cum BITE vehicle
