What is the resolution of the SAR ground range?

Ground range resolution of SAR refers to the ability to distinguish two points on the ground that are separated by a certain distance along the direction of the range, which is perpendicular to the flight path of the radar platform. It is determined by the bandwidth of the radar system and the geometry of the observation.

Ground range resolution is the measure of a radar system’s ability to distinguish between two targets on the ground that are spaced apart in the direction perpendicular to the radar’s line of sight.

It is influenced by factors such as radar bandwidth and angle of incidence.

SAR tilt range to ground range involves converting the distance measured along the radar line of sight (tilt range) to the horizontal distance on the ground (ground range). This conversion takes into account the angle of incidence and altitude of the radar platform to accurately map radar data onto the ground.

The resolution of the SAR image is determined by both the range resolution and the azimuth resolution.

The range resolution is defined by the bandwidth of the radar signal, while the azimuth resolution is influenced by the synthetic aperture length and radar wavelength. High-resolution SAR images can achieve sub-meter level details.

Radar range resolution is the minimum distance between two targets along the radar line of sight that can be distinguished as separate objects. It is primarily determined by the bandwidth of the transmitted radar signal, with a wider bandwidth providing finer range resolution
