Effects of Navigation Errors in Maneuvering SAR
James L. Farrell, James Mims, Almon Sorrell · IEEE Transactions on Aerospace and Electronic Systems · 1973
A maneuvering synthetic aperture radar in squint mode, during a loosely piloted maneuver, is simulated with presence of various navigation system errors. The error sources investigated place emphasis on short-term effects, involving platform servo transients, noise and quantization in accelerometers, interaction of angle pickoff uncertainty with the displacement from platform to radar antenna, and uncertainty in this displacement itself. Simulation results are accompained by interpretive discussion, and followed by suggested areas for further study.
