The velocities noted with the first pulse rate could be equal or different with the second. For instance, if the maximum velocity with a certain rate is 10 metre/second and the one with the other rate is 15 m/s. The data coming from both will be the same up to 10 m/s, and will differ thereafter. Latest weather radar images from the National Weather Service. NWS Doppler Radar.

Find Dallas-Fort Worth weather maps and interactive weather radar from NBC 5's certified Meteorologists. The distance to target has changed from times T1 to T2, resulting in a phase shift between the two return signals, which Doppler radars are capable of measuring. By knowing the phase shift, the wavelength and the time interval from T1 to T2, the distance D that the target has moved relative to the radar can be computed. The Doppler frequency depends on two variables: the aims radial speed and the carrier frequency of the radar transmitter. If the frequency of the transmitter is constant, then the Doppler frequency is a measure of the radial speed. Modern radars are frequency diversity radars mostly. Their transmitters frequency isn't constant. Doppler radars covering the Buffalo, New York area. Two Methods of Ambiguity Resolution in Pulse Doppler Weather Radars.
