Velocity This product is a Doppler Radar product that peers into the storm and allows meteorologists to see where the wind is moving toward the radar (red) and away from the radar (green/blue).
The red and green lines represent the motion trajectory in the radar coordinate system, while the gray line represents the motion trajectory in the main vehicle coordinate system. Within the range of 60 m to 100 m, the target points of multi-mode waveforms are notably denser compared to those...
For example, in Radar reflectometry and Satellite-based Radio Navigation system, the total time of propagation is used for calculating the distance. Therefore, in such applications any additional delay unaccounted for will lead to erroneous estimation of the range and will eventually cause errors in ...
For most of transparent materials, the refractive index is increasing with the frequency of the light. This means, that 1<n(λred)<n(λgreen)<n(λblue) or in general: (2.103)∂n∂λ<0, which is callednormaldispersion. However, in certain materials we see an opposite behaviour, ie,...

Techniques for accurately determining a velocity of a radar (or ultrasonic, sonar) device and/or a moveable platform associated with the radar device may comprise fitting a model to
If you click on the right arrow key a couple of times you can see that the same light is reaching "Speedy T" and "Captain Green" at the same time. But they have different interpretations of that light. The "actual" distances to the two space-stations is length contracted for "Speedy...
on rain gage-calibrated WSR-88D radar (Weather Surveillance Radar 88 Doppler) rainfall estimates (Fulton et al. 1998). These calibrated rainfall fields over the Niwot site were mor- phed with onsite precipitation. The model was run as a single point HRLDAS system to develop offline estimates...
Areas of high resistivity, relating to the bedrock, appear orange and red, whilst areas of lower resistivity, due to the overlying glacial deposits, appear green and blue. The deep area of overburden on the left of the image relates to infilling of a solution feature. The main application ...
