Speeding is one of the leading causes traffic crashes worldwide. Radar velocimeter widely used in capture monitoring road overspeed violations, which can effectively reduce probability accidents and protect people’s life property safety to greatest extent. As a new type radar velocimeter, multitarget (MTRV) monitor speed more than two vehicles at same time. However, verification method device M...

A new measurement technique is being developed by NASA to measure off-surface flow fields. This method, Doppler global velocimetry, will allow quantification of complex three-dimensional flow fields at video camera rates. The entire flow field structure within a selected plane is measured simultaneously rather than by scanned, point-by-point measurements using conventional laser velocimetry. To...
