Develop an unfurlable, electronically steered L/P-band synthetic-aperture-radar antenna for a small LEO satellite using origami-inspired fabrication to enable a flexible, deployable and potentially lower-cost design.

No. 349Problem statementDefence and aerospace

Active protection system (APS)

Abridged source description: develop an active vehicle-protection system using fast sensors and actuators to protect against anti-tank missiles or projectiles. The source allows electronic and physical countermeasures. Weapon-defeat mechanisms and implementation detail are intentionally omitted; this is not a complete technical specification.

No. 350Problem statementDefence and aerospace

Development of 4G/LTE based tactical local area network

Develop a 4G/LTE tactical local-area network for high-bandwidth real-time information exchange on moving platforms. It must support dynamic networking and integrate with existing radio and satellite links as part of the information grid.
