摘　　要：目前国内战场侦察雷达没有目标识别功能,判断目标类型是通过操作手分辨目标多普勒声音信号来实现的。然而,目标多普勒声音信号受噪声干扰大,操作手对目标尤其是对多目标进行判别非常困难,需要进行大量训练。为了提高目标类型的判断效果,采用伪彩色时频图方法进行目标判别,取得良好的效果。分析了某型战场侦察雷达视频回波特性,并对其进行了一系列处理,得到时频信息,用Matlab中Colormap建立伪彩色列表,以Visual C#为平台,采用GDI+方式对时频信息进行处理,实现了伪彩色绘图和位图的动态显示。At home, there is no target recognition function within battlefield reconnaissance radar. The target type is deci - ded upon by the operator with the assistance of the Doppler sound signal. But the Doppler sound signal is largely interfered by noise,it＇s very difficult for the operator to judge the target type and lots of training is compulsory. To improve the effect of target type recognition,the method of time- frequency graph with peusdo color is used for recognizing various targets. First, the paper analyzes the characteristic of the video frequency echo of some battlefield reconnaissance radar,and after a series of process, the time- frequency information is caught. Then, the Colormap function in Matlah is used for building the peusdo color table. Based on the bench of Visual C^# ,the GDI＋ method is used for processing the time- frequency information and the dynamic display of bitmap and the peusdo multicolor plot are all realized successfully.
