Unitary Space-Time Waveform Scheduling for High-Resolution Delay-Doppler MIMO Radar Sensing
… complementary sequences are very sensitive to Doppler, a scheme for Doppler compensation is proposed based on a data dependent weighting of the different PRI matched-filtered outputs prior to summing. The scheme is further improved to provide a reasonable estimate of the Doppler phase shift …

Development of Software to Measure the Gravitational Redshift with RadioAstron
… onboard H-maser frequency standard along with a Doppler compensation scheme that minimizes systematics, the gravitational redshift is anticipated to be determined with a relative accuracy of 10^-5. A third-order dynamical model has been implemented to predict frequency shifts in the spacecraft's …

Communication and time distortion
… asynchrony between clocks and motion-induced Doppler effects warp the time scale, while at higher layers there are packet delays. Current wireless underwater modems suffer a significant performance degradation when communication platforms are mobile and Doppler effects corrupt the transmitted …

Array Signal Processing for Communications from High Altitude Platforms and Other Applications
… of signals for accurate time-delay compensation. The OFDM signals from different directions are linearly combined after Doppler compensation and channel equalization. An adaptive Doppler filter is applied in frequency domain for removing residual intersymbol interference. The …
