查询词典 echo

In PC assisting, it can real-time generate radar video signal which display on real radar screen. It adopts the special arithmetic that generates a point by intersecting of two beelines. There isn t defect such as generating the radar video by table look-at bitmap. The radar image is more verisimilitude, and it is better to simulate sea echo suppression, anti clutter rain, etc.

它改变了以往采用位图形式查表实时生成雷达视频信号算法的缺点，采用从矢量化的海图数据中通过直线求交的算法实时生成雷达视频信号，这样在雷达显示的图像更加逼真，特别是在近量程，能真正提高雷达距离分辨力，不会出现马赛克现象，而且对于模拟诸如海浪抑制、雨雪干扰等更为方便。

We employ a computer to simulate the characteristics of objects and circumstance, and calculate radar video echo date, then through computer inter-face circuit and the relative circuit and D/A conveners, the echoes are outputted to a radar signal processor. The video signal simulator can be use to debug a terminal homing radar system instead of the former part of radar.

该模拟器通过计算机模拟目标和环境特性，产生雷达视频回波信号数据文件，然后通过微机接口电路、回放电路和D／A变换输出该视频信号，接至雷达信号处理机；它可以代替雷达前端对末制导系统进行调试；实验结果验证了该模拟器的有效性。
