摘　　要：探讨了探地雷达返回信号被采集到计算机中数据的处理方式,包括信号的实时滤波、实时杂波消除、信号实时成像处理、静态成像处理等。为了满足实时性要求,采用双缓存和DirectDraw技术相结合的方式实现实时成像,并就这些方式的一般处理方法给出一些改进方案。数据被实时筛选以后,采用GDI+技术实现数据的静态成像处理。This paper discusses some processing methods of GPR data which are sampling and transmitting to the computer, including real - time filtering, clutter dispeling, real -time signal imaging processing and static imaging processing. For the strict time demand,the double buffer area and DirectDraw technology to speed up the imaging procedure are utilized. The useful data are stored via the dynamic processing, which will bc refined with the GDI＋ technology statically.
