Abstract :
Inspired by compressed sensing theory, a novel radar system, called hybrid-frequency radar is proposed. It transmits multiple carrier-frequency modulated by random amplitude in each pulse, and can use much fewer pulses than that of stepped-frequency radar to achieve the same non-ambiguous range interval while the target is sparse spatially.
