1. Surveillance Radars
Battlefield Surveillance Radar – Medium Range
This radar is the state of the art ground surveillance piece of equipment, capable of automatically detecting and displaying various types of moving targets like vehicles, pedestrians, helicopter, and tanks. It supports artillery units with locating shell bursts and provides fire correction data.
Its applications are wide, including border surveillance, battlefield surveillance, intelligence gathering, artillery fire corrections, and protection of airfields. The most important features are:
Up to 40km and 360° detection and acquisition, easy transportation and deployment, 24-hour operating time under all weather conditions, pulse-Doppler radar, target classification based on Doppler tone, user-friendly menu with Windows 2000, low probability of interception, tracking while scanning 60 targets, overlay of digital maps, built-in training simulator, and provision to integrate with command and control systems.
3D Surveillance Radar – Rohini
This modern radar is designed to effectively deliver medium-range surveillance from the radar mounted on a mobile, truck platform. It operates in S-band and is capable of track-while-scan of various airborne targets up to 150 Km/s. These are its top features:
3D surveillance radar, ECCM features (side-lobe blanking, frequency agility and jammer analysis), integrated IFF Mk XI using extractor and co-mounted antennas, three mobile units on three vehicles, fully automated and controlled, user-friendly GUI, dedicated on-line BITE facility, data-remoting of tracks and plots to remote stations to through LAN, and data remoting of digital data link to remote data centers.
2. Fire Control Radars
All-Weather Low-Level Air Defense Weapon Control System
As a combination or a radar, computer and display, this machine deals with hostile threats at a top-level. Since it is on wheels, it is highly mobile. As its name suggests, this is an all-weather system, with timely detection, superb accuracy, and unimaginable tracking.
In addition, the device offers a fast prediction of lead angles and built-in counter-countermeasures. These are the top features of this radar system:
Early detection and fast acquisition, air Search in ‘I’ band, acquisition in ‘I’ and ‘Ka’ bands, dual b and ‘I’ and ‘Ka’ tracking, computer-assisted parallax calculation, ballistic data generation, track while scan up to 3 targets, color raster scan display with PPI and TV picture, tactical map presentation through a data input unit, built-in ECCM, and communication between system operator and gun.
3. Weapon Locating Radars
Weapon Locating Radar (WLR)
The radar has been primarily designed for locating hostile mortars, guns, and rockets that cause interference to the operations. In its secondary role, WLR tracks and observes the fall of shot from weapons, in order to correct the rate of fire.
The system is able to conquer data interference from a wide range of artillery, movement, and weather conditions. These signals are processed in real-time and extract required information for gunners in order for them to complete their missions successfully.
The advanced algorithms and state-of-the-art hardware come together to handle all of the detection, location and tracking of targets. It has the ability to locate enemy weapons and transmit this data to the counter fire elements for a retaliatory strike, before the target moves or escapes.
This is one of the key features of this radar. It uses a passive phased array along with the excellent sidelobe levels. The complete system is mounted on a TATRA vehicle, built to operate and excel in all terrains and weather conditions.
WLR is a joint project by radar house LRDE (DRDO) and Bharat Electronics (BEL), developed to fulfill the long-time necessity of the Indian Army.
4. Secondary Surveillance Radars
IFF Mk-XII
Often overlooked, the secondary surveillance radars tend to play a major role on the battlefield, even if they are never used. It is always necessary to have a backup system in case the primary is destroyed or in other ways incapacitated. The top features include:
Solid-state transmitter, state of art component, RDP Interface (LAN / RS 422 / RS 232), menu-driven control unit, and target report available on the control unit.
