Doppler notebook 承接距离处理,开始解释速度信息从哪里来�?
关键思路
- 单个 chirp 主要给距�?
- 多个 chirp 之间的相位变化揭示速度
- 如果目标在多�?chirp 时间尺度内保持相对稳定,就可以从慢时间维估计 Doppler
工程含义
多普勒估计让雷达从“看见物体在哪”进化到“看见物体怎么动”�?
English
The Doppler notebook builds on range processing and explains where velocity information comes from.
Key idea
- A single chirp mainly gives range
- Phase evolution across multiple chirps reveals motion
- If the target stays coherent over the slow-time dimension, Doppler can be estimated from chirp-to-chirp changes
Engineering meaning
Doppler estimation upgrades radar from knowing where an object is to knowing how it is moving.
