This paper discusses the Synthetic Aperture Radar for Open Skies (SAROS), an airborne side-looking synthetic aperture radar (SAR) system installed on the U.S. OC-135B Open Skies Observation Aircraft. The paper discusses in detail how the SAROS is designed to meet the performance requirements and limits of the Treaty on Open Skies. The SAROS is based on the U.S. AN/APD-12 analog radar system which has been modified to digitally record radar, motion, and annotation data on magnetic tape and has been designated as the AN/APD-14. The theoretical performance of the AN/APD-12 SAR exceeds the three meter range and azimuth resolution allowed by the Treaty. The SAROS design will limit the performance of the SAR to no better than three meter`s through reduction in transmitted frequency bandwidth, reduction in azimuth bandwidth, and decimation of azimuth sampling prior to recording of the phase history data. 5 figs.
