Design and implementation of space target ISAR imaging display and control terminal

显控终端是雷达系统的重要组成部分,为雷达操作用户提供雷达系统控制操作与目标信息的显示。本文介绍了一种基于VS2010编译环境的空间目标ISAR成像显控终端。该显控终端使用专用硬件实现雷达目标回波信号的实时采集与接收,采用CPU与GPU异构并行处理机制完成回波数据的实时ISAR成像处理及结果显示。最终在通用PC上实现了包括系统参数设置、高速回波数据的实时接收与存储、实时ISAR成像处理及空间目标一维距离像、二维ISAR像的输出与显示。

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 realtime echo data,the real-time ISAR imaging process and the display and output of one-dimension distance image and twodimension distance-orientation image on a common PC.
