谢谢,那我还想问一下我导入数据到matlab中,显示的是100*3*64*64的数据格式,3可能代表是三根天线、两个64是一帧64个chirp 每个chirp64个采样点,这个100是什么呀。 或者说怎么处理这个数据呀,后续不知道怎么变成二维矩阵,100是帧数吗,有点蒙圈

Hi Griffin,

你的理解是对的,100*3*64*64分别代表:

RX :3

per chirp :64 simples 

frame: 64 chirps

100 frame

使用matlab plot 可以看到fft后的图像如下:

建议参考Radar-Fusion-GUI的相关HELP文档,

SDK里面有数据格式存储以及如何处理的示例代码:

Hi Griffin,

感谢你在英飞凌技术社区的积极提问!对此,我们有一些小小的建议:

由于本界面是英文界面,你在本界面的提问都会统一被送到国外的工程师那边进行回答,但是由于提问内容是中文,所以这些问题又会再次转手给国内的工程师进行回答,这样反而会耽误你获得答案的时间。因此,我们建议你在中文界面中进行提问,这样方便我们的工程师分配对应的FAE 进行回答。

要切换到中文界面,你可以直接点击右上角的语言选择,勾选“CN-简体中文”即可。 

谢谢!
