Modeling Pulse-to-Pulse Coherent Doppler Sonar

Journal of Atmospheric and Oceanic Technology, 2008
Abstract Coherent Doppler sonar provides a powerful tool for probing boundary layer flows under field and laboratory conditions. However, velocity profiling applications of this technique are complicated by characteristic velocity and range ambiguities. Proper implementation for any application requires careful design so that performance

Tiger stripe: an innocuous Doppler artifact

Echo Research and Practice
Background Tiger stripes, parallel bands within regurgitant Doppler spectra, are often ascribed to oscillating intracardiac structures. Their frequency and clinical relevance are unclear.
