Interferometric Synthetic Aperture Radar (IFSAR or InSAR) is a remote sensing method that exploits phase differences between two or more coherently acquired SAR images to derive precise topographic and surface deformation information. Using either single-pass (across-track baseline) or repeat-pass geometries, IFSAR forms an interferogram from complex SAR data, from which relative phase is unwrapped and converted to line-of-sight height or displacement through known radar geometry and baseline vectors. The method requires accurate calibration, coregistration, and error mitigation (e.g., atmospheric phase delay, decorrelation), and is widely employed for digital elevation model generation and geodetic-scale deformation monitoring.
Plants often grow spines, thorns and prickles to defend against animals that feed on them, but why this happens in some places more than others has remained a mystery. Research in New Phytologist shows that plant spininess ...
