描述了一种基于软件的方法，用于估计和补偿调频连续波雷达中的线性调频脉冲非线性。该方法基于相位梯度算法和去线性调频信号的时域扭曲。该方法在典型和严重非线性线性调频信号上进行了演示。回顾性应用在存档雷达数据上进行了演示。
A software-based method for estimating and compensating for chirp non-linearity in frequency-modulated continuous wave radars is described. The method is based on the phase-gradient algorithm and time-domain warping of the dechirped signal. The method is demonstrated both on typically and severely non-linear chirps. The retrospective application is demonstrated on archive radar data.
