Abstract :
A Ku-band radar has been developed for detection and tracking of sniper rifle bullets and other ballistic projectiles. The radar utilizes a novel retrodirective architecture based on separate 8-element receive and transmit antenna arrays. A pseudorandom noise waveform provides for precise ranging and high processing gain. Digital filtering allows for discrimination of high-velocity bullets and small supersonic projectiles up to at least 1700 ft/s, as demonstrated experimentally in field tests.
