NISAR Beta Geocoded Polarimetric Covariance Product is a Level 2 radar dataset derived from Level 1 Single Look Complex data. It provides terrain-corrected polarimetric covariance matrices projected onto a UTM or polar stereographic grid. The data is produced by the NASA-ISRO collaboration and distributed by the Alaska Satellite Facility (ASF).
This is a Beta product collection intended for user familiarization with parameters and formats, not for scientific research. The polarimetric covariance matrix is Hermitian, so only the upper triangular terms are provided in the data.
