Abstract

A programmable instrument for the simultaneous measurement of velocities and acceleration or deceleration of different objects becomes possible through the use of spectral analysis of the Doppler signal. Programmable gain and frequency synthesis is under software control. Spectra for different segments of the Doppler time series are displayed versus time. When scaled, velocity versus time is displayed. By integration, velocity versus distance could also be displayed. Curve fitting is applied to chosen segments so that velocity and acceleration or retardation can be calculated. The raw digitized Doppler signals as well as calculated results are stored on disk for further off-line review and editing
