中文摘要: |
本文结合自适应Roth时延估计器和拷贝相关器,提出了一种既可以检测多亮点目标回波,又可以在低采样频率下(采样间隔ms级),精估μs级方位时延的广义自适应拷贝相关器算法。并进行了深入的理论分析,完成了计算机仿真:验证了该算法具有较高的处理增益和参量精估精度,很适合于检测和高分辨精估目标多亮点的方位、距离和多卜勒。从而为尺度识别奠定了基础。 |
英文摘要: |
This paper proposes a generalized adaptive duplicate correlation algorithm based on the adaptive Roth time delay estimation and duplicate correlation. This algorithm can detect the echo wave of a multiple light-spot target. This paper also proposes a way of accurately estimating the directional time delay on as level at low sampling frequency, offers theory analysis, and accomplishes computer simulation. That the algorithm has high processing gain and excelent estimate precision has been Verified. The algorithm can be used for detect and highly resolve the direction, distance, and Doppler frequency shift of multiple light-spots and lays a foundation for scale identification. |
