Abstract: Multi-carrier spread spectrum radar is presented. In the multi-carrier spread spectrum radar system, phase difference is used to measure the object range and the Doppler shift is used to measure the velocity of the object. Multi-carrier spread spectrum radar has the advantages of higher performance of anti-narrow band interference and lower peak average ratio. Simulation results show the effectiveness of the proposed radar system.

Key words: radar, spread spectrum, multi-carrier modulation
