What are the two types of passive Missile Approach Warning System (MAWS)?

The correct identification of the two types of passive Missile Approach Warning Systems (MAWS) is rooted in understanding how these systems detect incoming threats. Ultraviolet and Infrared detection methods are integral to MAWS because they focus on identifying missile signatures based on the emissions they produce.

Ultraviolet sensors are adept at detecting the intense heat and light emissions from missiles, particularly during the boost phase of their flight. This early detection can provide critical response time to mitigate threats. In contrast, Infrared systems work by sensing the heat emitted by a missile’s engine or its exhaust plume, allowing for tracking and identification once the missile is in flight.

In summary, both types of sensors—Ultraviolet and Infrared—are essential for the function of passive MAWS, enhancing situational awareness and enabling defensive measures against missile threats.
