In version 2013 and earlier software process radar data in ERDAS IMAGINE Radar Mapping Suite. The software contains several modules that allow you to work with radar data in ERDAS IMAGINE. Radar mapping is known for precise geolocation and the ability to provide detailed information that cannot be extracted from traditional optical imagery - day or night, rain or shine.
IMAGINE Radar Mapping Suite provides tools to geocode, orthorectify, despeckle, and calibrate radar images. The IMAGINE SAR Interferometry module automates coherent change detection, DEM extraction, and subsidence mapping to centimeter-level accuracy.
