The phrase "angular extent" is correct and usable in written English.
It can be used in contexts related to geometry, physics, or astronomy to describe the measure of an angle or the range of angles covered by an object or phenomenon.
Example: "The angular extent of the star cluster was measured to be approximately 30 degrees in the night sky."
Alternatives: "angle range" or "angular range".
Camera viewable angle α describes the angular extent of the scene viewed by the camera.
It visualizes the degree of coherence in phase space as the angular extent.
The block is centered at the angle Θ and has an angular extent Δ Θ.
However, more effective control over the amplitude and angular extent of the generated response pattern is provided by the anisotropy.
However, the width of the peaks in the angular spectrum is also influenced by the angular extent of the partially coherent source.
On the other hand, some discrepancies between CORSET and the automated catalog were found, which can be explained by the different delimitation of the CME angular extent.
Significant speed-dependency of the characteristic events that are generated at the angular extents of the defect are shown by simulation and experimental measurements.
When considering the same longitudinal and latitudinal extents for both the outer boundary and mid-depth patches, a root (at mid-depth) of an intense flux patch (at the CMB) would exhibit an apparent distortion due to the difference between the corresponding CMB and mid-depth areas of equal angular extents.
They interpreted this as an implicit measure of an increase in the perceived distance for a situated observer: The angular horizontal extent of the object was unaffected optically; thus, the greater perceived width seemed to be due to an increase in the apparent viewing distance (see Fig. 3).
Finally, we demonstrate that the propensity for nano-ductility is primarily controlled by the extent of angular flexibility between the rigid polytopes of the network.
The performance of MIMO system is greatly affected by the extent of the angular dispersion of angle of departure (AoD) and angle of arrival (AoA), which is described by the angular spread (AS) in the existing channel models.
