Ultra-wideband Synthetic Aperture Radar landmine detection based on landmine-enhanced imaging

Metrics to evaluate compression algorithms for raw SAR data

“…A very short pulse enables high resolution since the distances are measured more accurately [42]. The main advantages of UWB operation are improved resolution and more information about the reflectivity of the targets in the scene [42, 43]. Imaging through unconventional mediums: The applications of UWB SAR include uses in the military and civilian domains.…”

“…In the military domain UWB radar is used for foliage penetration, ground penetration and through‐wall detection [44, 45]. The ground penetration capabilities of UWB SAR make it highly affective for the detection of landmines [43]. Popular civilian applications include the monitoring of oil reservoirs [46], by imaging the perforations or fractures in the well, and medical imaging, like the detection of tumours [47].…”

“…The image quality depends strongly on the measurement accuracy and the dynamic range of the system [42]. For landmine detection, regions of interest are identified by measuring the amplitude difference between targets and the background noise [43]. To avoid a high number of false alarms, the noise in the system should be minimised.…”
