The Defence Research and Development Organisation (DRDO) has developed a Portable Target Echo Simulator (PTES) to test its X-band missile seeker. X-band seekers are commonly used in anti-ship missiles.

Radio Frequency Gimballed Seeker, RPF and Altimeter system have been developed for various tactical missile systems including Beyond Visual Range Air to Air Missile (BVRAAM) Astra and Akash-1S.

The DRDO has also developed other seeker technologies and products, including:

Ku-band RF Seeker for Anti-Aircraft applications
X-band RF Seeker for Anti-Ship applications
Radio-Proximity Fuse systems (RPF)
Radio Frequency Gimballed Seeker
RPF and Altimeter system
Ceramic/Composite Radome

Imaging Infra-Red (IIR) Seeker systems have been successfully flight tested in Anti-Tank Guided Missiles Nag, HELINA and MPATGM. IIR Seekers have also been successfully demonstrated in the Exo-Atmospheric Interceptor PDV and Anti Satellite Test (ASAT), Mission Shakti.
