Spaceborne imaging radar research in the 90's [PDF]

open access: yesAdvances in Space Research, 1987
The imaging radar experiments on SEASAT and on the space shuttle (SIR-A and SIR-B) have led to a wide interest in the use of spaceborne imaging radars in Earth and planetary sciences. The radar sensors provide unique and complimentary information to what is acquired with visible and infrared imagers.

Using ground radar overlaps to verify the retrieval of calibration bias estimates from spaceborne platforms [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
Many institutions struggle to tap into the potential of their large archives of radar reflectivity: these data are often affected by miscalibration, yet the bias is typically unknown and temporally volatile.
