SAR high-resolution imaging from missing raw data using StOMP

SAR high-resolution imaging from missing raw data using StOMP

SAR raw data missing occurs when radar is interrupted for various reasons. In order to deal with this problem, a method is proposed to focus the missing SAR raw data via stage-wise orthogonal matching pursuit (StOMP). A reference function in time domain is designed for the missing raw data. After ma...
