Non-cooperative bistatic SAR missions such as SAOCOM-CS promise to greatly enhance the science return of existing missions at a low cost.
In this study, we addressed major technological challenges associated with the implementation of such missions, such as phase calibration and tomographic focusing.
The research methodology was as follows:

The evolution of space technology has allowed ESA to consider new possibilities for challenging and groundbreaking mission that impose new and complex requirements and constraints both on the ground and space mission segments.

Plastic marine litter is becoming a major environmental concern. Microwaves (MW) have potential for remote detection of floating macroplastics operating from Satellites or Airborne platforms, but very scarce and limited studies exist in the literature using MW. We present the first results of a systematic study on MW scattering of floating low-mass macroplastics at 2-20 GHz frequency band using radar techniques.
