Abstract
New approaches to designing highly accurate laser Doppler measurement systems (LDMS) are presented. They are based on the concept of instantaneous frequency of the analytical Doppler signal, the algorithms of its maximum likelihood estimates, and the principles of tracking filtering. LDMS based on those principles is described and results of its metrological investigation and applications in an aerodynamic experiment are presented. The adopted engineering solutions are presented and substantiated.
