Abstract: The heat deform ations of a real satellite antenna m ust be detected inground. A sim ulative testing on a sm allm odelof antenna using Electron Speckle Pattern Interferom er is reported. The w hole field dynam ic deform ation caused by heatis obtainedw ithoutspecialvibration isolation. The results show that it is possible thatthe E S P Iandthe inform ation treatm ent m ethods are used for realtim e m easure of a realsatellite anten na.
