Retrodirective Noise-Correlating Radar in X-Band

Abstract

This project entails the design, construction, and demonstration of an X-band noise correlating radar with a retrodirective antenna. Preliminary simulations of this system indicate that it should provide the following benefits: (1) approximately 5-times reduction in acquisition time compared to traditional electronically-steered search-mode radar, and an even greater reduction in comparison to mechanically scanned radar; (2) a significant reduction in probability-of-intercept compared to traditional search radars based on coherent transmitters; and, (3) a significantly reduced cost and greater simplicity since several of the most expensive components in traditional radar - coherent oscillators, T/R modules, and precision phase shifters - are completely avoided by the proposed approach. The prototype RNC radar will have four channels, each channel having a complementary transmit/receive antenna pair. The antenna type is a printed-circuit patch. The electronic gain connecting the receive and transmit antennas will be roughly 100 dB, all derived from commercial-off-the-shelf (COTS) components.
