Azimuth Sidelobes Suppression Using Multi-Azimuth Angle Synthetic Aperture Radar Images [PDF]
Sensors, 2019 A novel method is proposed for azimuth sidelobes suppression using multi-pass squinted (MPS) synthetic aperture radar (SAR) data. For MPS SAR, the radar observes the scene with different squint angles and heights on each pass.

APPLICATION OF EFFECTIVE AZIMUTH DIFFERENT FORMULA IN DETERMINING THE QIBLA DIRECTION
Al-Hilal, 2023 The sun's shadow and the Qibla azimuth are two techniques for figuring out the Qibla direction. To obtain Qibla direction accuracy while applied to traditional instruments with low accuracy, such istiwa'ayn, the user's accuracy is required.

COMPARISON OF MICROWAVE BACKSCATTER ANISOTROPY PARAMETERISATIONS OVER THE ANTARCTIC ICE SHEET [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 The Antarctic Ice Sheet exhibits a strong anisotropy in microwave backscatter, both as a function of azimuth angle and incidence angle. This anisotropy arises as a result of i) the alignment of roughness elements and other wind-related surface and sub ...
