摘要
由于电子海图、雷达图像及二次目标的数学基础不同 ,简单地把它们分层显示存在较大的误差。分析了误差产生的原因 ,提出了对误差进行修正的叠加显示方法 。
There are some algorithmic differences in manipulating and display methods among the electronic chart, radar image and targets. In this paper, for superimposition display among the electronic map, radar image and targets, the main reason of display error is analyzed and the solution of error-correction is proposed and validated.
