摘　　要：介绍了嵌入式仿真技术及其发展,将嵌入式仿真与雷达模拟训练相结合,构成了能够嵌入到机械扫描雷达实装的模拟训练系统。描述了对嵌入式仿真训练系统的结构组成以及部分模块的功能,研究了模拟雷达视频回波数据的方法和模型,包括目标回波、地物杂波、海杂波、气象杂波、有源干扰和接收机内部噪声,利用数学模型计算回波的强度、方位、距离等特性,调制实际录取的回波数据,生成与态势设置参数相应的模拟回波数据,能够对信号处理操作和抗干扰操作做出响应。通过对视频回波进行仿真,由终端显示画面可知模拟的回波数据具有较高的逼真度,经测试模拟视频回波能够被雷达显控终端识别。The technology and prospects of embedded simulation was introduced. The combine embedded simulation and radar training system make up of simulation training system that can embed in mechanical scanning radar. The structure and function of embedded simulation radar training system were introduced. The method and model of radar video echo were studied, which included target echo, ground clutter, sea clutter, weather clutter, active jamming signal and intemal noise of the radar＇s receiver. The mathematical model was used to calculate the intensity, azimuth, distance of echo characteristic and produce simulative echo data according to state setting parameter by modulating actual echo. The training system can respond signal processing and anti-interference operating. By simulating video echo the image of radar display showed that simulative echo had high fidelity and could be identified by Radar terminal.
