Abstract:	A real-time Synthetic Aperture Radar (SAR) requires accurate measurement of the motion of the radar antenna with minimal latency to produce well-focused images. Sinusoidal measurement errors of only 1 degree of radar phase (0.025 millimeters) can produce unacceptable sidelobe levels in the radar imagery. A two-axis precision positioning system has been modified to score inertial navigation systems (INS's) outdoors. Results are presented for two real-time SAR motion measurement systems, one that uses a tactical-grade IMU and the other, a navigation-grade IMU.
