WebJul 7, 2024 · An FMCW chirp consists of an electromagnetic wave that’s ramped up in frequency linearly over a period in time. These signals are transmitted and reflected by objects and received. In general, an FMCW transmitted chirp can be expressed as: x (t) = Ac * cos ( (wc + Ab * t) * t) (1) Web对fmcw信号进行理论推导分析，描述毫米波雷达数据的2dfft数据梳理方法以及各个维度之间的关系 FMCW基本原理 2024年3月20日22:06:57更新_haoming Hu的博客-程序员宝宝 - 程序员宝宝
