What is a Software Defined Radio (SDR)?
- SDR is a radio communication system that employs reconfigurable software-based components for the processing and conversion of digital signals.
- Unlike traditional radio communication systems, these radio devices are highly flexible and versatile.
- This is an emerging technology used to connect ever-increasing wireless world.
About Software-Defined Radio Tactical (SDR-Tac):
- Equipped with several multimedia capabilities, the indigenous SDR-Tac provides real-time voice, data and video information.
- It is built indigenously by the Navy’s Weapons and Electronics Systems Engineering Establishment (WESEE).
- What does SDR-Tac do?
- SDR-Tac is a four-channel multi-mode, multi-band, 19-inch rack-mountable, ship-borne software-defined radio system.
- It is intended to serve ship-to-ship, ship-to-shore, and ship-to-air voice-data communication for network-centric operations.
- It supports the simultaneous operation of all four channels covering V/UHF- and L-Band.
- This SDR system houses multiple types of waveforms for narrow-band and wide-band applications.
- Each ship will act as a relay wherein the data can jump from one ship to another.
- To transfer voice, data or video, the link device picks up the best-suited available network. It ensures that data reaches its destination.
