CALPRO™ is a general purpose calibration processor for SAR data, capable of performing calibration operations for ALOS-PALSAR, ENVISAT-ASAR, Radarsat, ERS1/2 and JERS1.
CALPRO™ has been deployed at ERSDAC, Japan for generating calibration results such as antenna patterns and timing offsets for the several acquisition modes of the ALOS-PALSAR sensor.
CALPRO™ will be deployed for generating calibration results for the upcoming Lunar missions involving the Forerunner and LRO SAR instruments.
CALPRO™ imports the space agency standard Level 0 formats as well as Vexcel STF and Vexcel Level 1 data formats for estimation of antenna patterns, absolute gains, polarimetric distortion matrix coefficients and gain, phase imbalances and saving the results in the payload file format specified for the sensor being calibrated.
CALPRO™ interfaces seamlessly with payload file formats used by Focus™, Vexcel’s SAR processor. A user-friendly GUI allows for raw or Level 1 data ingest, production, display and saving of calibration results.
