The display and control terminal is an important part of a radar system.It provides radar system control operations and displays the target information for users. This paper introduces a display and control terminal for space target ISAR imaging based on VS2010. In order to receive the broadband echo signals in real time, this display and control terminal samples and receives radar target echo signals by using dedicated hardware. Besides,it uses CPU and GPU heterogeneous parallel processing to complete echo data ISAR imaging process and the displaying of imaging process result. Ultimately,this terminal achieves the setting of system parameters,the storage of the high speed realtime echo data,the realtime ISAR imaging process and the display and output of onedimension distance image and twodimension distanceorientation image on a common PC.
