测量速度: 经过CFAR检测之后然后检测峰值确实会得到Range 和Doppler的峰值索引,也就是多个chirps测速法,但是最大不模糊速度为十几m/s,在实际使用中并不满足需求超出不模糊速度就会产生速度模糊,因此需要对速度扩展,中国余数定理是很好的速度扩展算法,对速度进行解模糊。后面博客会对讲解中国余数定理原理和在雷达中的应用...
To achieve the Spatial vs Doppler frequency plot, you can utilize a 2D FFT (Fast Fourier Transform) to extract and visualize the relationships between spatial frequencies and their corresponding Doppler shifts. In the existing implementation, the ranges for 'Ax' and 'Ay' can lead to overlapping ...
