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...
This paper focuses on the performance of a retrodirective noise correlating radar using a novel analytic tool - the retrodirective matrix (RM). The RM couples the transmit array to the receive array through free space, and when combined with band-limited electronic feedback becomes part of a loop analysis that is useful in analyzing the transformation from random noise to quasi-coherence, and in predicting...
