resolution in azimuth

resolution in azimuth

[‚rez·ə′lü·shən in ′az·ə·məth]
(engineering)
The angle by which two targets must be separated in azimuth in order to be distinguished by a radar set when the targets are at the same range.

The high resolution in range direction is obtained by the pulse compression of the initial chirp signal and the high resolution in azimuth direction is derived from the movement of the platform--an airline or a satellite [6].

A synthetic aperture can be derived through the movement of antenna, and the higher resolution in azimuth will be obtained.
However, in conventional SAR systems, high geometric resolution in azimuth and wide swath (HRWS) [1] coverage imposes contradicting requirements on system design: a high azimuth resolution requires a large Doppler bandwidth, which has to be sampled with a sufficiently high pulse repetition frequency (PRF).
This imaging mode results in higher Doppler bandwidth signals for a high resolution in azimuth than that in stripmap SAR.
