Time and Frequency Transfer in a Coherent Multistatic Radar using a White Rabbit Network
… time and frequency transfer (TFT) for range and Doppler estimation. TFT techniques based on global navigation satellite systems (GNSS), have been favoured for several reasons, such as enabling node mobility through wireless operation, geospatial referencing, and atomic clock level time and …

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 …

High Resolution Continuous Active Sonar
… focuses on methods for achieving high range, Doppler, and angular resolution, while maintaining a high signal-to-interference plus noise ratio (SINR).</p><p>CAS systems transmit at or near 100\% duty cycle for improved update rates compared to pulsed systems. For this reason, CAS is …

Doppler spread estimation in mobile fading channels
The Doppler spread, or equivalently, the mobile speed, is a measure of the spectral dispersion of a mobile fading channel. Accurate estimation of the mobile speed is important in wireless mobile applications which require such as knowledge of the rate of channel variations. In this dissertation, …
