Bistatic Airborne SAR acquisitions with MetaSAR-L

March 26, 2019

Our airborne SAR processing experts, Karlus Macedo and Gerard Masalias, attended the ESA “Bi- and Multistatic SAR Systems and Applications” workshop at TUDelft.

 

We presented the latest results of the airborne bistatic SAR campaign, ESA BelSAR, conducted with two independent airborne SAR flying on two separate aircrafts.

 

Each aircraft was carrying the MetaSAR-L configured in fully polarimetric mode and each aircraft was transmitting and receiving acquiring at the same time monostatic and bistatic interferometric data in polarimetric mode.

 

The polarimetric image in Figure 1 shows the response to different backscattering mechanisms from agricultural fields, urban and forested areas.

 

Figure 1: Bistatic Polarimetric image over southern Belgium. The color composite (red (VV), blue (HV) and green (HH) highlights the different backscattering mechanisms from agricultural fields, urban and forested areas. The SAR image has a ground swath of 2.4 km and length of 6.6 km.

 

 

Figure 2: a) coherence and b) interferogram acquired in bistatic formation with a 25-meter cross-track baseline. Despite having two independent receivers, the images show that coherent phase information is obtained from the bistatic formation and good coherence is obtained over non-forested areas.

We thank the organizing committee composed by ESA and TUDelft staff for the excellent, innovative and very interesting workshop.

Thank you to all the attendees for their scientific contributions and the valuable discussions.

See you to the next edition.
