摘　　要：根据水下目标定位跟踪的系统功能,设计了用于水下目标被动定位跟踪的综合显示系统,能够实现信号的特征显示、轨迹跟踪处理和目标轨迹识别。采用B式瀑布图显示技术、目标航迹跟踪技术以及基于Hough变换的航迹信息提取技术,仿真分析和实验数据表明,该显示系统的设计可以提高被动定位跟踪综合显示性能。For locating and tracking underwater targets, an integrated information display system, including signal character display, target tracking and trajectory recognition, is designed. Major techniques contain B type display, target tracking filter and trajectory information classification via Hough transform. Simulation and experiments show that with the integrated information display system more information can be displayed for target detection and classification, and the performance of the passive sonar can be improved.
