To detect the moving targets such as cars or ships, we developed along-tack interferometric SAR (AT-InSAR) system and added its function on NICT airborne SAR. Our AT-InSAR can measure the moving targets in the single (VV) and dual (VV and VH) polarization. The dual polarization mode has more degree of freedom compared to the single polarization mode. The preliminary experiment for verifying its performance carried out on the farm road. First of all, to arrange the triangular and square trihedral corner reflectors in the azimuth direction, we checked and confirmed the performance of AT-InSAR antenna. Then, we checked its ability to indicate the moving target by observing the truck running toward the range direction at a constant velocity. Finally, we verified the accuracy of its velocity estimated from AT-InSAR data and clarified that its velocity was estimated from VV AT-InSAR data highly accurately. [ABSTRACT FROM PUBLISHER] |
