Analysis of an X-Band Retrodirective Noise Correlating Radar for Large-Caliber Bullet and Projectile Detection

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 the radar detection time and range as a function of array size and electronic gain
