Abstract :
The traditional phase compensation method based on parametric model always needs to make a tradeoff between the accuracy and the computational complexity. Given this, a new method for compensating phase based on Discrete Polynomial Transform (DPT) and CLEAN technique is proposed. To reduce the computation power further, the imaging region estimation is applied. Furthermore, the limitation and the restricted condition of DPT are analyzed for practical scenarios in this paper. In the end, simulation results are given to validate this method.
