工具与软件：
尊敬的 TI 社区：
我当时使用 rawdatareader.m 生成 radarcube.mat 文件和使用 MATLAB 生成 FFT 图、但我得到的输出与 mmWave Studio 的 postproc 不同。 我认为它在运行该脚本时可以识别不同的 adcbin 文件。
我使用的线性调频脉冲配置与 mmWave Studio 中的常用配置不同。
您知道如何获得与 mmWave Studio 相同的 FFT 图和时域信号、但只使用 rawdatareader.m 脚本吗？ 我是否必须更改 json 文件或脚本本身中的一些参数？
请告诉我。
谢谢。此致、
Niladri
尊敬的 Cesar：
感谢您的友好回答。 我真的很抱歉这么晚才回复。
我要附加 mmWave Studio 中的线性调频脉冲参数和输出图。
我还附带这里的 json 文件、并且是从 mmWave Studio 获得的。
第1个是设置 json 文件、第2个是毫米波 json 文件。
使用这2个 json 文件、我无法使用 rawdatareader.m 脚本读取二进制文件。
谢谢。此致、
Niladri
