雷达航迹数据压缩方法研究

A Track Data Compression Method for Use on Radar

目前雷达情报数据传输以短波电台和光纤通信为主,这些传输手段遭到破坏后通信容量将会极大降低。为解决低通信容量下的航迹数据传输问题,提出了一种基于航迹数据曲线拟合的数据压缩方法。雷达探测目标得到点迹,然后将点迹关联形成航迹,先对航迹进行曲线拟合得到拟合曲线参数。通过传输拟合曲线参数来代替传输航迹数据,最终利用拟合曲线参数恢复出航迹,从而极大压缩数据传输量,完成在低通信容量下的雷达航迹数据传输。

Currently radar data transmission mainly depends on the short-wave radio and fiber- based communications, thus the destruction of the means of transmission will greatly reduce the capacity of communication. To solve the problem of track data transmission at low data transmission capacity, we proposed a data compression method based on track data curve fitting. Target detected by radar was taken as trace point, then the trace points were associated to form a track. Curve fitting was made to the track to obtain the parameters of the fitted curve. Then, the parameters of the fitted curve were transmitted instead of the track data. Finally, the parameters of the fitted curve were used to recover the track, which could greatly compress the data traffic, and implement radar track data transmission under the condition of low transmission capacity.
