距离
中文
Range notebook 试图把“目标距离是如何从单�?chirp 的回波里提取出来的”讲清楚�?
重点
- 距离是雷达最基础的输出量之一
- 单个 chirp 的回波里已经编码了目标距离信�?
- 通过适当的采样与频域处理，可以把“时间差 / 频差”映射到距离 bin
它在处理链中的位�?
距离处理通常是整�?DSP 链的第一步，后续 Doppler �?AoA 基本都建立在 Range 结果之上�?
English
The Range notebook explains how target distance can be extracted from the return of a single chirp.
Main points
- Range is one of the most fundamental radar outputs
- Distance information is already encoded in the return of a single chirp
- With suitable sampling and spectral processing, timing / frequency differences can be mapped into range bins
Pipeline position
Range processing is usually the first DSP stage, and later Doppler or AoA steps are built on top of it.
