Abstract : A photogrammetric resection technique is used as a basis for the initial calibration of a ground based radar (ASFIR). An analysis of the influences of errors in camera calibration and geodetic bias is developed. The errors in range and azimuth from the ground stations to the aircraft are computed using the results from a stellar calibration performed on the camera. The results confirm earlier predictions that the photogrammetric error contribution to error in range (standard error) amounts to about 1 part in 10,000 of the flying height along each coordinate axis. This error is to be augmented with the geodetic bias error estimated to be + or - meter at 400 kilometers. (Author)
