A rotating antenna Ground-Based SAR

In this paper a rotating antenna GB-SAR, that we named RotoSAR, has been proposed and tested. The radar head is fixed at a rotating arm and the antennas are aimed in direction orthogonal to the rotation plane. The obtained results both in simulation and in-field tests, show that imagery quality performances are comparable to the linear SAR. On the other hand, the proposed approach is potentially much more faster than conventional Ground Based linear SAR.
