Fmcw测距代码
WebFMCW radar is less affected by the noise in comparison to impulse radars. 2.1FMCW radar basics In any radar, the electromagnetic wave is sent into the environment containing various objects. Then the echo of the wave is captured at a receiver. A simplified block diagram of such a system is shown in Fig. 1 in which both the Webfmcw雷达探测具体是如何实现的呢？ 调制连续波雷达也被称为频率调制连续波（fmcw）雷达，是一种能够使用称为频率调制的技术来测量目标的范围的系统。在频率调制中，电磁波的频率随时间线性增加。换句话说，发射的频率将以恒定的速度变化。
