Hybrid low-frequency and high-frequency radar system

Abstract

A hybrid radar system includes one or more low-frequency antennas configured to receive low-frequency reflected energy resulting from reflection of low-frequency transmissions, and one or more high-frequency antennas configured to receive high-frequency reflected energy resulting from reflection of high-frequency transmission. A frequency of the high-frequency transmissions is at least 1.5 times a frequency of the low-frequency transmissions. A processor obtains and processes one or more low-frequency digital signals resulting from the low-frequency reflected energy received at each of the one or more low-frequency antennas and one or more high-frequency digital signals resulting from the high-frequency reflected energy received at each of the one or more high-frequency antennas. The processor controls an operation of the vehicle based on information obtained by processing the low-frequency reflected energy and the high-frequency reflected energy.
