The following SAR Image quality parameters are indicative of ICEYE SAR sensors, which is representative for performance of satellites developed by ICEYE.
General Radiometric Performance
The ICEYE SAR processor compensates the following effects:
Relative Radiometric Accuracy is the standard deviation of the radiometric error of known targets within one data take. Contributions come from the antenna pattern, the pointing knowledge of the antenna pattern and drifts of the instrument during operation. The relative radiometric accuracy estimate is < 1 dB for Stripmap data.
Pixel Geolocation Accuracy
For satellite path oriented (SLC and GRD) products, the pixel geolocation accuracy is primarily determined by the system performance on orbit. For orthorectified and value added products, also the quality of DEM (particularly vertical accuracy) should be taken into account.
Predicted orbit is obtained using the latest post-processed GPS data propagated to the acquisition time. Rapid orbit is obtained as a result of post-processing of GPS data during the ground station pass and provided for processing / georeferencing of the imagery. Typical orbit accuracy levels of small SAR satellite developed by ICEYE as as follows:
