摘　　要：提出船用雷达回波视频信号模拟器上位机软件中的核心部分,即雷达回波视频数字序列的产生方法。该方法根据雷达分辨率模型、雷达回波信号模型、海杂波和噪声模型,以极坐标扫描模拟海图的方式生成雷达回波视频数字序列。通过将算法相关模型加入到MATLAB中仿真、画图并对实验结果进行比较和分析,验证了以上述方法生成雷达回波视频数字序列是可行的。通过将数字序列下载到船用雷达回波信号模拟器板卡后输出较逼真的雷达回波视频信号,验证了船用雷达回波信号模拟器可以完成对于船用雷达回波信号的模拟。验证结果表明,船用雷达回波模拟器系统有助于雷达系统对雷达回波信号特征进行分析研究,有助于雷达后级系统设计的参数优化研究,对改善雷达系统系能具有重要的参考价值。A method of the generation of a radar echo video digital sequence is proposed, which is the core of the software of Marine radar echo video signal simulator. This method generates the radar echo video digital sequence by the way of polar-coordinates scanning according to radar resolution model, radar echo signal model, sea clutter model and noise model. Marine radar echo simulator outputs radar echo video signal by downloading the digital sequence which verifies the feasibility of the method. Experimental results show the contribute to echo signal＇s characteristics of radar system, also contribute to the radar system parameter optimization design which provides a great value to improve the radar system performance.
