正态分布随机数在航迹模拟数据中的应用

The Gauss Distributing Random Data and Its Appliance in the Track Simulating Data

在超低空预警组网航迹模拟数据产生器中,采用面向对象的语言获得随机数做为测量噪声,能使产生的航迹数据与雷达测量数据比较接近,而达到理想数据的测量噪声符合正态分布。如果采用取舍法产生正态分布随机数,可产生具有均匀性和独立性探测器量测数据。由此高斯分布随机数作为测量噪声加在理想数据上,便能完成对探测数据的模拟。

In the track simulating data generator of overlow air alert net,in order to approach the radar measure data,the random data is engendered by the face object language.The ideal data is add to the measured random and produces the measuring data.The random data is in accordance with Gauss distributing,and has equality and independency.The random data is produced with the method of accepting or rejecting date on the basis of Gauss distributing theory.The result is checked on the equality and independency.It is satisfied and successful to simulate the flying target track by the detector and to generate the point data.
