DARPA seeks sensors for smart shells
DARPA is looking for radio-frequency (RF) seekers for smart shells.
The goal is sensors accurate and rugged enough for DARPA's Multi-Azimuth Defense-Fast Intercept Round Engagement System, or MAD FIRES, smart shell program. "Current projectile technologies have been demonstrated in flight maneuver, but only recently have advances in electronics and gun survivability opened the possibility of projectile-based seekers," explains theDARPA research solicitation.
RF seekers are a promising solution, but current seekers are too big for medium-caliber projectiles. "The antennas must reside within the outer mold line of a medium-caliber projectile and survive gun launch and ballistic fly out," DARPA said.
