Results of the first calibrated Doppler measurements taken with a Doppler Asymmetric Spatial Heterodyne (DASH) instrument optimized for measuring simulated upper atmospheric winds using the O(1D) red line at 630nm will be presented. A space flight prototype DASH instrument has been designed, built, and is currently operational through funding from the Air Force Research Laboratory (AFRL) and in-kind support from the Naval Research Laboratory (NRL). The DASH instrument named ARROW (Atmospheric Redline inteRferometer for dOppler Winds) includes an internal emission line source for simultaneous calibration of the Doppler shift measurements, measured a laboratory emission line source which was Doppler shifted by known velocities. The comparison between the Doppler shifts that were retrieved from the DASH data and the shifts that were imposed on the laboratory emission line source demonstrate the accuracy of the measurements. This laboratory validation contributes significantly to our efforts to rapidly increase the technical readiness level of the DASH optical interferometric technique.
