船舶导航雷达目标回波信号特征分析

Analysis of marine radar target echo signal characteristics

利用实测记录的雷达目标回波视频信号对不同目标的回波面积、形状复杂度和幅度相关性等特征参数的统计特性进行分析.结果表明,同一目标的特征参数具有较强的相关性和稳定性,可以用于雷达目标检测和跟踪算法,有利于提高检测和跟踪性能;也可以用于雷达目标模拟,使模拟的雷达目标信号特性更接近真实目标回波信号.

The analysis of characteristics of marine radar target echo signals, including the area, correlation of the shape complexity and the amplitude of the target echo signal, was conducted by using the recorded radar video signal. Results show that the characteristic parameters of the same target ap- pears strong correlation and stability. Thus these characteris- tic parameters can be employed to the target detection and tracking algorithms to improve the performances. It can also be used in radar target simulation to make the simulated radar target echo signals looks more close to the real ones.
