A radar device for measuring the surface velocity of water moving in a horizontal plane in which the radar device is positioned above or below the horizontal plane. The radar device includes a tilt sensor, or accelerometer, to measure the angle of tilt of the radar device with respect to a...
PROBLEM TO BE SOLVED: To suppress interference effects from other radars and to enable the computation of the relative distance to and relative velocity of a target by using the combinations of the results of measurement of the relative distance to and relative velocity of a target at a pluralit...
An Interferometric Moving Target Indicator (MTI) radar can be used to measure the tangential velocity component of a moving target. Multiple baselines, along with the conventional radial velocity measurement, allow estimating the true 3-D velocity of a target. 展开 ...

guns.SARandISARimaging radarsmake use of Doppler frequency to generate high-resolution images of terrain and targets. TheDoppler frequency shiftalso has been used in Doppler-navigation radar to measure the velocity of the aircraft carrying the radar system. The extraction of the Doppler shift in ...
HF radar sounding of the ionosphere provides the possibility to monitor the ionospheric Doppler plasma velocities and consequently the electric field. The dense array of SuperDARN radars in both Northern and Southern hemispheres makes it possible to measure the ionospheric electric field response in conju...
one microsecond can measure the range to an accuracy of a few tens of metres or better. Some special radars can measure to an accuracy of a few centimetres. The ultimate range accuracy of the best radars is limited by the known accuracy of the velocity at which electromagnetic waves travel...
PROBLEM TO BE SOLVED: To dispense with radar reflected signals of many continuous scans, and to acquire wave information on the wavelength, the wave velocity, the wave direction, the wave height or the like, accurately from the radar reflected signals of continuous two scans in wave measurement...
