摘要

本文提出了一种相干霍夫方法对脉冲序列信号进行积分。该方法基于窄带回波模型，在进行霍夫变换之前，先对脉冲间调制相位项进行补偿，实现相干积分。改进后的方法优于标准霍夫变换，特别是在非常低信噪比的环境中。分析了算法的性能，并通过仿真实验进一步验证了算法的有效性。

A modified coherent hough method for pulse-train signal integration

A coherent Hough method is proposed here to integrate the pulse-train signal. Based on a narrowband echo model, the suggested method implements the coherent integration by compensating the modulated phase terms from pulse to pulse before applying Hough transform. The improved method outperforms standard Hough transform, particularly in a very low SNR environment. The algorithm's performance is analyzed and its validity is further verified by simulation experiments.
