As reported by ANI India bags a 40 Million dollar deal to supply Swathi Radars to Armenia beating Russian and Polish firms. In this article let’s discuss about Swathi Radar.
Specification of Swathi Radar
As you know there are many types of Radar some are used to detect Aircrafts, some used in to detect Warships or some detect Missiles just like this Swathi is a Weapon Locating Radar (WLR). It is use to locate weapons firing from enemy.
Swathi WLR 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.
If we talk about detection range then it has the potential to detect 81 MM Mortars at the range of 2-20 KM. 105 MM Gun at 2-30 KM or it can detect Guided rockets in between 4-40 KM.
Swathi 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.
Army chooses this System to replace its US based AN/TPQ 35/37 WLR System. As of now there are 28 system is on order by Army.
