Saab offers sensor package for India's Tejas LCA Mk1A fighter aircraft


Saab is offering a sensor package for India's Tejas LCA Mk1A fighter aircraft in partnership with Indian industry.

The package comprises a Saab airborne electronically scanned array (AESA) fighter radar integrated with a compact electronic warfare suite using Gallium Nitride (GaN) based AESA technology.

Saab Surveillance business area head Anders Carp said: “In our partnership, the transfer of technology will secure an indigenous Indian capability for series production, maintenance, repair and overhaul capability.

“Testing and development of the fighter sensor package will have synergies with the systems developed for Gripen.”

Saab said that the AESA fighter radar is developed using antenna technology based on the latest technologies using GaN) and Silicone Carbide (SiC) substrates in combination with the exciter/receiver and processor technology.

The radar's complete mode suite consists of air-to-air, air-to-ground and air-to-sea capabilities.

Designed to provide essential situational awareness and self-protection, the EW suite includes sensors and transmitters, as well as an external AESA jammer pod.

"Testing and development of the fighter sensor package will have synergies with the systems developed for Gripen."

The jammer pod's Wideband Digital RF Memory (DRFM) provides advanced jamming techniques and arbitrary combination of jamming waveforms.

The suite also features an electronic warfare receiver that is connected to a front end receiver and fin tip antennas inside the aircraft, as well as ground support systems and recording capability for advanced mission planning and post-flight analysis.

Built by Hindustan Aeronautics Limited, Tejas is a single-seat, single-engine, lightweight, high-agility supersonic fighter aircraft that can be armed with air-to-air, air-to-ground and anti-ship missiles, precision-guided munitions, rockets and bombs.
