A system for generating a corrected azimuth signal for a radar system having a radar antenna and a radar display where the radar antenna is mounted on a craft that is subject to motion and that has a stable reference source. A digital computer is connected to the stable reference source of the craft for receiving signals representative of the crafts roll, and representative of the crafts pitch. The digital computer processes the signals representative of roll and pitch utilizing a correction algorithm in order to generate an azimuth correction signal. This azimuth correction signal is combined with the radar azimuth signal by means of the crafts solid state control differential transmitter. The output of the solid state control differential transmitter constitutes a corrected azimuth signal and is furnished to the display of the radar system. The display thus generated by the radar system pursuant to target detection thus accurately represents the true azimuth of the target. Patents. sdw
