Abstract

This paper describes a Bragg Cell Interferometer (BCI) that is designed to measure a signal''s amplitude and phase spectrum precisely. The output of the BCI can be applied to a Superresolution range-Doppler estimator. It is shown that by using the Fourier Transform outputs, the estimation of range-Doppler from scatterers is transformed into a 2D sinusoidal frequency estimation problem, whose frequencies correspond to range and Doppler. Hence, superresolution techniques based on linear prediction may be applied to estimate the range-Doppler of scatterers with great accuracy.
