Claim One:
1. A frequency data extrapolator, comprising: memory; and processing circuitry, configured to: receive input frequency data mapped to a two-dimensional frequency grid, the input frequency data based on return signals received at a sensor in response to pulsed transmissions of the sensor in a physical environment; classify regions of the frequency grid as high fidelity or low fidelity based at least partly on fidelity measurements of the input frequency data: determine a group of basis rectangles within the high fidelity regions; determine a column-wise extrapolation matrix and a row-wise extrapolation matrix based on the input frequency data of the basis rectangles; generate a two-dimensional extrapolation of the input frequency data of the high fidelity regions to replace the input frequency data of the low fidelity regions, based on the column-wise extrapolation matrix and the row-wise extrapolation matrix; and generate output frequency data for usage in determination of a parameter of the physical environment, based on the two-dimensional extrapolation.
