Abstract: The theory and method of designing radar signal with MAC-sequence-code are systematically studied in this paper. Both theoretic analysis and simulation results show that MAC-sequence is a binary sequence with ideal correlation property and ability of anti-shelter effect. MAC-sequence-coded radar signal is a practical signal with good LPI feature and can be used to measure the distance and velocity unambiguously. -
