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。
In this paper, an adaptive Roth time delay estimator and a copy correlator are proposed, which can not only detect multiple bright-spot target echoes but also estimate the generalized μs-level azimuth delay at low sampling frequency (sampling interval ms) Adaptive Copy Correlator Algorithm. And the in-depth theoretical analysis is carried out. The computer simulation is completed. The algorithm has high processing gain and precise parameter estimation. It is suitable for detecting and resolving azimuths, distances and Doppler of multi-bright targets. Which laid the foundation for the scale recognition.
