The phrase "angle elevation" is not correct in standard written English.
It may be intended to refer to "angle of elevation," which is a term used in trigonometry to describe the angle between the horizontal line and the line of sight to an object above the horizontal.
Example: "To calculate the height of the building, we measured the angle of elevation from a distance of 100 meters."
Alternatives: "angle of elevation" or "elevation angle."
Thus, the kth azimuth angle, elevation angle, and coupling coefficient estimates are automatically matched.
Because of the special geometry of forward scatter radar, parameters (i.e., Dopplershift, azimuth angle, elevation angle) cannot directly be measured when the targetcrosses the baseline, resulting in a large estimation error and seriously decreasing thetracking precision.
As a matter of fact, once the system declares the presence of a target, its resources are scheduled to estimate target parameters [1, 2] or for target tracking [3] which consists in the fine estimation of parameters as range, azimuth angle, elevation angle, and Doppler frequency offset.
After being placed in the supine position in bed, with head angle elevation at 30°, patients were randomized to: group 1 (G1): vibrocompression for 10 minutes in the chest, or group 2 (G2): vibrocompression plus increase of 10 cmH2O in IP in PSV for 10 minutes in the chest.
Bland-Altman plots showed that the greater the angle of elevation, the greater the mean difference between goniometer-set and SMA-derived elevation angles.
(A typical beamwidth might be about 1 degree). Such a radar system can determine the location of the target in both azimuth angle and elevation angle.
Computers then figure a track's correct curvature and angle of elevation and feed the information to machines that put the rail and ties into place.
Then UCA-ESPRIT algorithm can be used to estimate the transmit azimuth angle and elevation angle.
Simulation results show that the proposed algorithm for sparse UCA can obtain good azimuth angle and elevation angle estimate results.
Two different similarity functions are chosen to search for azimuth angle and elevation angle, respectively, in this algorithm.
