Retrodirective noise-correlating radar at X band: first demonstration of small target detection

This paper reports the realization of a four-channel retrodirective noise correlating radar operating in X band around 10 GHz. It is designed for rapid detection of small targets at short range. Detection times less than 50 ns are demonstrated for a 30-caliber bullet, and the autotracking capability of the RNC radar is demonstrated for the first time with the bullet in motion.
