BGT60TR13C的默认脉冲重复周期(PRT)是多少,录制数据显示frame_repetition_time_s=0.1633s,RADAR GUI显示Frame interval=0.078s

您好,

如图所示,斜率S=Bw/Tc, Tc是chirp的持续时间,也就是之前您贴图的tc: chirp time.在Radar Fusion GUI的配置中,是通过sampling rate结合Samples Per chirp来进行配置。

Hi @shybreak 

  • PRT是chirp重复时间(也叫脉冲重复周期),是指两个chirp之间的时间间隔。
  • 在Radar Fusion GUI中,对应Chirp Repetition Timejulis_0-1709518521930.png
  • frame_repetition_time_s对应Radar Fusion GUI中的Frame Rate的倒数,表示帧间隔。

该问题不属于XMC范围,请在sensor类别下选择radar创建,其他两个帖子同理。

我的理解是如图所示 PRT== Chirp repetition time +toff (图中的toff)Griffin_0-1709557657876.png

这个图来自RADAR FUSHION GUI的用户指南

nini您好,@shybreak 

如图所示,PRT = tprt = tc + toff,tc和toff一起表示一个chirp重复周期,即PRT。

另,若回答了您的疑惑,请将答案标记为解决方案,其他两个帖子也同理。

谢谢

这么理解的话,PRT知道了,我的参数tc就求不出来了,对于配置Chirp的斜率S=BW/tc也无法求解,或者换种问法就是BGT60TR13C的tc是多少
