基于圆概率误差的定位精度评定办法

圆概率误差(CEP)常用来表示炮弹、导弹命中精度和导航定位精度。它有几种不同的定义及简化计算方法,若不根据具体使用情况对样本数据进行分析而采用简化公式进行计算就容易导致错误,因此,详细分析了圆概率误差的几种定义、简化计算方法及各自的适用范围,从最基本定义出发,利用Matlab编制了计算软件,并以某型无人机侦察装备定位精度试验数据为例进行了实际计算,结果表明计算方法正确可靠,能准确评价被试装备的定位精度。

Research on positioning accuracy evaluation method

CEP is used to describe the shooting accuracy of cannonball, missile or positioning accuracy of navigation. It has several different definitions and corresponding different calculation methods. If not according to the specific use of the sample data and use the simplified calculation formula to calculate CEP is easy to cause the error. The definition, calculation methods and application range of CEP was analyzed in this paper, from the most basic definition, based on the Matlab calculation software, the calculating software of CEP was programmed. An example of CEP calculation was given on the data of orientation precision test of one type of reconnaissance equipment and the calculation results show that the calculation method is correct and reliable, it can accurately evaluate positioning accuracy of test equipment.
