Chaff

From Peace Station Encyclopedia

A combination of both aerial radar and aerial infrared countermeasures designed to foil radar-guided/heat-seeking missiles. Chaff is typically released via a specialized dispensor designed to create a cloud of small, thin pieces of aluminium, metallised glass fibre, plastic or other materials. This cloud creates a swarm of secondary targets on any radar screen or masks the area by providing multiple returns detected on radar. Decoy flares are launched to attract the attention of incoming missiles, while the targeted vehicle turns away from the direction of the flares and attempts to produce as little heat from the engines as possible. These systems can help to defeat hybrid missile tracking systems.
