英文摘要： Combined with the application of Unmanned Underwater Vehicle (UUV) flank array and with the signal integration of targets detection and communication, we will focus on the underwater target detection based on the non-circular signal to improve the performance of underwater target detection. By exploiting the non-circular property, the optimal design methods of transmitted waveform for underwater targets active detection will be proposed in this project and the methods of UUV flank array underwater target detection for the non-circular signal will be given. Also, the theory of Multiple-Input Multiple-Out (MIMO) array will be studied. The non-circular techniques will be proposed for DOA estimation by UUV flank MIMO array. Finally, the water tank and lake experiments will be conducted to evaluate the performance of these proposed methods. The achievements of this project can improve the performance of underwater targets detection for UUV flank array. All these achievements not only be used in acoustic homing system and sonar system, but also be extended for radar, navigation, and other related fields.
