Another SAR aided guidance system developed by Boeing for the US Navy, uses target cueing based on Synthetic Aperture Radar/Ground Moving Target Indication (SAR/GMTI) imaging, which automatically extracts information for JDAM targeting. The information received from the airborne surveillance sensor, to continuously track mobile targets and send targeting cues via data-link, in real-time, to JDAM weapons after release, on their way to the target. The accuracy of such system is expected to be up to 1 meter CEP, considerably improved over standard GPS targeting.
