Licensed under CC BY 4.0 International DATA & FILE OVERVIEW File Name: 'Cranfield_University_GBSAR_Laboratory_Data_Boat_Model' The dataset contains multistatic fully polarimetric SAR phase-history measurements acquired using the Cranfield University Ground-Based SAR (GBSAR) laboratory system. Measurements include HH, HV, VH, and VV polarisation channels collected over an X-band frequency range (8-12 GHz). The dataset is provided as a MATLAB structure array containing phase-history measurements, radar trajectory coordinates, and associated sensor parameters used for SAR image formation via back-projection imaging. Included trajectories comprise both target motion-inverted SAR trajectories used to produce ideally focused SAR imagery and uncorrected trajectories corresponding to unfocused imagery. Supporting parameters include total number of pulses, number of frequency samples, centre frequency and bandwidth. Are there multiple versions of the dataset? No METHODOLOGICAL INFORMATION Description of methods used for collection/generation of data: The dataset contains SAR measurements collected by the Cranfield University GBSAR Laboratory System. Methods for processing the data: The Cranfield University GBSAR Laboratory System stores SAR measurements in the form of Scene (.scn) files, which were converted to MATLAB file objects and stored in the form of ".mat" files. Instrument- or software-specific information needed to interpret the data: MATLAB 9.14.0.2239454 (R2023a) People involved with sample collection, processing, analysis and/or submission: Anmol Rattan and Daniel Andre DATA-SPECIFIC INFORMATION FOR: [FILENAME] Number of variables: 1 MATLAB structure array containing 30 MATLAB Variables Variable List: 1.
