ConclusionsConclusions
Bistatic SAR with fixed ground receivers allows to develop affordable complete SAR chains suitable for hands-on SAR training and multichannel SAR research
A multichannel X-Band SAR receiver has been designed by undergraduate students from low cost COTS monolithic devices
First results on Barcelona harbor using TSX illumination has shown the importance of acquiring clean direct channel replica and channels H(f) calibration/equalization for accurate range compression and InSAR
Metallic containers and ships produce very bright scattering centers even at wide bistatic angles
The cost of high speed digitizers is presently the main bottle-neck for budget multichannel operation. A PRF trigger is under development for longer acquisition at highest sampling rate
