Fast Azimuthal Displacement Retrieval from TOPSAR Burst Overlapping Interferometry: Application in Dronning Maud Land (Antarctica)
peer reviewed Differential SAR Interferometry allows deriving velocity maps only along the line of sight. Bi-dimensional displacement estimation may be overcome using TOPSAR mode acquisition. TOPSAR acquisition mode implies burst-by-burst acquisition with beam steering from backward to forward durin...

peer reviewed Differential SAR Interferometry allows deriving velocity maps only along the line of sight. Bi-dimensional displacement estimation may be overcome using TOPSAR mode acquisition.
