ABSTRACT:
A system and method for extrapolating sampled radar data allows in one aspect spectral data to be increased without increasing scan time and in another aspect allows scan time to be decreased without decreasing radar data quality. Extrapolation is carried out by extending a sequence of In-Phase and Quadrature-Phase samples by appending additional samples to each end of the sequence. Extrapolated samples are selected to maintain the statistical properties of the original sequence. Applying conventional windowing techniques to the extrapolated sample set results in a weighted extrapolated sequence having a corresponding Doppler spectrum with an increased spectral resolution.
