我想问下，为什么我这样设置参数，在40米到50米左右的目标，没有显示出来，我想知道我哪个参数设置不合理，还有我想问一下，Duty Cycle为什么不可以设置成100%？

从日志中似乎您正在使用旧版本的mmWave studio，请使用最新版本的mmWave studio。 如果仍然发现错误，请发布Studio屏幕截图和日志。
对于线性调频配置，您可以参考以下链接的TI resource explorer文件夹中的Chirp database:
http://dev.ti.com/tirex/explore/node?node=ALYHkY2xyhq2-EgWIUuw-Q__VLyFKFf__LATEST
这为各种应用程序线性调频配置提供了指针。 可以根据您的需求进行调整和修改。
100％的占空比不现实，主要是因为：
器执行数据处理的功能，即多普勒FFT，到达角处理，检测和更多后处理功能，具体取决于客户用例需求，这些元素需要在帧间隔和线性调频间隔之间进行一定的时间分配。 在实时嵌入式系统中，这些数据需要处理和使用，因此在占空比百分比较高（50 +％）的情况下，您可能没有足够的时间进行处理。 因此，100％的占空比是不现实的。
在更高的占空比下，传感器也会消耗更高的功率，从可靠性的角度来看，这对于长时间运行而无需为设备提供热保护将是一个问题。
