基于排序加权法的雷达宽带视频显示控制方法

Radar broadband video display and control method based on sorting and weighting

目前显控台大多采用嵌入式操作系统,该平台不具备高级绘图工具,并且对大规模宽带视频数据较难识别目标。针对以上问题,本文提出一种采用基本绘图函数,通过排序加权法实现宽带视频显示控制的方法。该方法首先根据显示区域的长度、数据的距离分辨率和量程,把宽带数据与显示单元分段对应;然后采用排序加权法对逐个数据段进行处理,以达到突显目标幅度的目的;最后通过基本绘图函数进行绘图显示,从而实现对回波的显示与控制。通过试验验证,该方法在保证可靠性和实时性的前提下,不仅准确、直观的反映了回波特性,而且大大提高了对目标的人工辅助识别能力。

The embedded operating systems are mostly used on display consoles at this point, but such platforms are not provided with advanced graphic software, without which targets are difficult to be identified in the case of large-scale broadband video data. In view of these problems, a broad- band video display and control method is proposed based on the sorting and weighting method and the basic graphic functions. Firstly, according to the length of the display area, range resolution and range scale, the broadband data segments are made to correspond to the display units. Secondly, sorting and weighting is used to process the data segments one by one in order to highlight the target amplitude. Finally, the plotting display is done and then the echo display and control are realized through the basic graphic functions. The test verifies that the echo characteristics are reflected accu- rately and visually and the capability of the manual aided recognition is increased significantly through the above method on the premise of assuring high reliability and real-time performance.
