Infrared Focal Plane Arrays developed by DRDO perform which function in a tactical missile?
- A.They provide thrust in the boost phase
- B.They encrypt the data link to the launch platform
- C.They act as sensing elements for detecting and tracking the target
- D.They generate electrical power for onboard systems
Correct answer
Explanation
The correct answer is that they act as sensing elements for detecting and tracking the target. Infrared Focal Plane Arrays were described as the eyes of tactical missiles: working through an imaging infrared seeker, they allow the missile to find and follow its target during the terminal phase of flight, and the exhibits covered the short-wave, mid-wave and long-wave infrared bands. Option A confuses them with a propulsion element such as the scramjet engine technology, which DRDO displayed separately at the same event. Option B describes a communication and cryptography function, and option D describes a power source, neither of which is the role of a focal plane array. Aspirants should pair this with the other semiconductor family on display, the Monolithic Microwave Integrated Circuits on gallium arsenide and gallium nitride, which are the building blocks of radar and electronic warfare systems.
