1. A method of processing radar signaling, the method comprising:
receiving the radar signaling, wherein the radar signaling comprises a first matrix of data having a first dimension and a second dimension, wherein the first dimension represents a fast-time axis and the second dimension represents a slow-time axis;
receiving a mask that represents samples in the radar signaling that are detected as including interference, wherein the mask comprises a second matrix of data having the first dimension and the second dimension, wherein the first dimension represents the fast-time axis and the second dimension represents the slow-time axis;
applying the second matrix for the mask to the first matrix of the radar signaling in order to provide interference-reduced-radar-signaling, wherein the interference-reduced-radar-signaling comprises a third matrix of data having the first dimension and the second dimension, wherein the first dimension represents the fast-time axis and the second dimension represents the slow-time axis;
performing frequency analysis on the third matrix for the interference-reduced-radar-signaling across each of the fast-time axis and the slow-time axis in order to provide a range-Doppler map of the interference-reduced-radar signaling;
performing frequency analysis on the second matrix for the mask across each of the fast-time axis and the slow-time axis of the mask in order to provide a range-Doppler processed mask; and
deconvolving the range-Doppler map of the interference-reduced-radar-signaling using the range-Doppler processed mask in order to provide a deconvolved-range-Doppler map.
