Ultrasonic Multiple Target Detection and Anti-Interference Based on Polyphase Orthogonal Sequence

摘要：

The system based on spread spectrum technology can gain excellent measure precision under low power density. Therefore, ultrasonic multiple target detection using spread spectrum technology can not only gain excellent measure precision, but also resolve the conflict between detection distance and resolving power. The polyphase orthogonal sequence has ideal auto-correlation property. So it is very fit for using in ultrasonic multiple target detection. In this paper, the ultrasonic multiple target detection system based on polyphase spread spectrum technology is proposed. The interference in multiple target detection and anti-interference in this system are analyzed. The detection precision and the target number being detected can be highly improved in this system.
