Waveform Design for Improved Doppler Accracy

Abstract

A waveform design procedure for improving the estimation of Doppler frequencies in active remote sensing applications is presented. The bound on frequency estimation is analyzed in terms of a continuous waveform, and the optimal waveform is inferred. Several waveform designs are analyzed, showing that a near-optimal dual-pulse waveform can achieve greater estimation accuracy than a single-pulse waveform using the same signal energy.
