摘要： A method of processing radar data comprising: receiving a mask that identifies a set of samples in received radar signalling that are detected as including interference, and comprises a matrix of data having a fast-time dimension and a slow-time dimension; receiving radar data comprising a matrix of samples of received radar signalling having a fast-time dimension and a slow-time dimension wherein the set of samples identified by the mask have been set to a predetermined value to remove said samples including interference; determining a reconstruction of the radar data in which at least the set of samples of the radar data are replaced with estimated samples, wherein said determining a reconstruction of the radar data comprises formulating an optimization problem based on the radar data and the mask, and applying an iterative method to solve the optimization problem at least in part in the range-Doppler domain.
