India commences the delivery of Swathi Weapon Locating Radar to Armenia nearly 10 months after Armenia signs a deal with India to deliver 4 units at the cost of $40 Million.

The first set of BEL Swathi Weapon Locating Radars (WLRs) were seen loading on to a Russian Air Force Antonov An-124 transport Aircraft at Bengaluru Airport on 22 January.

As per an airport official, another unit of Swathi WLR is again seen today on the Bengaluru Airport. Most likely India will deliver all the 4 units to Armenia in coming weeks.

During Armenia-Azerbaijan war, many Pakistani twitter user spreads a fake news that Swathi WLR failed to locate Azerbaijani drones during conflicts which costs huge damage to Armenian forces.

However, Armenia didn’t used any Swathi WLR Radar during conflict in September as they didn’t have any unit. Delivery was due to begin from November, which later pushed to January by India due to CoVID.

Even if India accelerated the delivery, then also it will require at least 1 year to fully operationalize the system for war.

Swathi Weapon Locating Radar

Swathi Weapon Locating Radar (WLR). It is use to locate weapons firing from enemy.

Swathi Weapon Locating Radar has been jointly developed by Electronics and Radar Development Establishment (LRDE), a lab of Defence Research and Development Organisation (DRDO) and Bharat Electronics Limited (BEL) and installed on a truck produce by BEML (Bharat Earth Movers Limited).
Swathi use for locating Mortars, Artillery Shell’s and Rockets.

It has a instrumented range of 50 KM and can handle multiple targets at a time, if fire from different weapon platform.

Swathi WLR uses C Band frequency to track targets and has a 0.9 Probability of detection. It can stored 99 weapon location of enemies.

It can operate in temperature between -20 to 55+ degree Celsius. It can easily operate up to 16,000 feet or 5KM approx.

It has the potential to detect 81 MM Mortars at the range of 2-20 KM. 105 MM Gun at 2-30 KM and Guided rockets in between 4-40 KM.

Swathi WLR use Passive Electronically Scanned Array Radar which is derived from Akash, Rajendra Radar. It can track 7 targets simultaneously. Efforts are going on to upgrade it with active array (AESA) to enhance performance and reliability.

It is Slewable up to +/-135° within 30 Sec which means 360° in less time. It use 40 KW power to transmit beam.

This WLR uses Monopulse signals to track targets and to process these signals it use pulse compression technique, Which enhance the signal ranges and also the resolution of the signal. It also reduce noise in the signal. Technically Swathi WLR is low probability to intercept.
