Synthetic aperture radar (SAR) monopulse angle measurement is an adequate method of target angle measurement in low signal‐to‐clutter and noise ratio. However, there is a contradiction between the instantaneous angle measurement and the SAR coherent accumulation. In this study, the authors use the total variation method to solve the above problem, and propose the monotone iterative method to enhance the efficiency of the total variation method, which is verified in the simulation.
