Abstract
Radar is one of severe interferences for spread spectrum communication system. A time-symbol level interference analysis methodology from radar to spread spectrum communication was proposed. Firstly, the electromagnetic interference mechanism from radars to spectrum spread communication system was analyzed based on time-symbol level, and the error bit rate formula of spectrum spread communication system in the presence of pulse radars interference was concluded. The performance of interference from pulse radar to spectrum spread communication system was simulated by the radar electromagnetic interference model, which proved the theory analysis result. Finally the frequency-distance relationship of five general radar and spread spectrum communication system in microwave band was calculated. The results show that this interference analysis method well exhibits the interference essence of radar and improve the frequency utilization efficiency.
