The Midcourse Space Experiment program will launch a satellite with several optical surveillance sensors onboard that will observe targets launched separately in dedicated and cooperative target programs. The satellite is scheduled to be launched in 1994 and the targets will be observed in several missions over the ensuing eighteen months. The Early Midcourse Target Experiments Team is developing ground based software that will process data to collect target signature phenomenology and demonstrate key surveillance system functions of the IR sensors during the early midcourse phase of a ballistic missile trajectory. Satellite sensor data will be transmitted to the ground and hosted at the Early Midcourse Data Analysis Center (EMDAC). The Early Midcourse Data Reduction and Analysis Workstation (EMDRAW) is a testbed for the algorithm chain of software modules which process the data from end to end, from Time Dependent Processing through object detection and tracking to discrimination. This paper will present the EMDRAW testbed and the baseline algorithm chain.
