基于电子海图的雷达回波信号仿真

Radar Echo Signal Emulation Based on Electronic Sea Chart

雷达回波信号的仿真是雷达模拟器模拟显示的基础。提出并构建了"扫描数据表"和"扫描地图数据表"及基于它们和电子海图高程信息的雷达回波信号模拟算法,实现了雷达回波信号的模拟,仿真了电磁波遮挡效应和雷达波束角宽度对雷达回波信号的影响。此方法运用于某型雷达模拟器的雷达回波信号仿真,通过普通PC计算机仿真显示,验证了此方法的有效性。

The emulation of radar echo-signal is the base of radar simulation display.Scan Data Table and Scan Map Data Table were proposed and then come to be established.On the basis of them and the elevation information of electronic sea chart,a radar echo-signal emulation algorithm was given.Then,the radar echo signal was simulated successfully,the blocking effects of electromagnetic waves and the effects of radar beam on radar echo signals could be emulated.These tables and the method involved have been applied for emulating the radar echo signals of one radar simulator,whose effectiveness has also been indeed proved in the way of conventional PC computer emulation.
