Figure 11(b) shows the cross-section of the PSF, from which it could be seen that the angular resolution is about 1.
Abstract: Progress in high angular resolution techniques in the infrared (Adaptive Optics and Optical Interferometry) provided a wealth of new observaions of the circumstellar environment of evolved stars in their immediate vicinity.
Equation (6) shows that the angular resolution is determined by the coverage of the visibility function samples, while Equation (5) shows that the anti-aliasing FOV is determined by the grid spacing among the visibility function samples.
Frequency scanning is an intermediate technique between beam scanning methods that provide good range and angular resolution and the use of an antenna with a constant beam direction, which only provides range resolution.
From formula (5), it is seen that at constant angular resolution [gamma] linear resolution d is connected with altitude by proportional dependence.
This allows us to noticeably increase the angular resolution near the direction of mirror reflection.
The angular resolution of a sonar system is determined by the width of the beam pattern - the narrower it is the better.
In order to synchronize the velocity measurements with respect to the location of the lobs (blades), a shaft encoder that provides a pulse per revolution and 3600 train pulses, giving an angular resolution of 0.
Both horizontal [1] and vertical focusing lead to a loss of angular resolution via peak broadening, for they increase the vertical divergence of the beam incident on the sample.
