Abstract :
Aimed at the need of high-resolution SAR motion compensation, a high-accuracy FOG-IMU, which includes a high-precision and low-ripple power module, a high-precision signal acquisition module based on FPGA and the related algorithm, is designed and realized, and then integrated into POS. A lot of tests show that the system is stable and reliable. And the applications of POS in the motion compensation of SAR imaging demonstrate the high precision of the system.
