您正在使用什么可视化工具？ 你能分享你的 cfg 吗？

3.不可能显示一个点,对象将具有来自多个点的反射  

您好！

我感谢重播、并将使用 SRR_visualization 可视化工具。

我将在下面附上 CFG。

您好！

  温柔的提醒...

谢谢！

尊敬的 Sriram：

澄清一下、SRR 实验(lab0002_short_range_radar)适用于 AWR1642BOOST EVM。 您是否使用演示的修改版本在 AWR1843BOOST EVM 上运行？

谢谢！

Jin

您好！

  温柔的提醒...

谢谢！

你好

感谢您的答复。 我会尝试将 SRR 实验室从 AWR1642更改为 AWR1843、但没有功能。 请帮助您进行修改。

谢谢！

尊敬的 Sriram：  

Sriram、您能说明哪些功能不起作用吗？ 虽然我们没有将 SRR 实验室从 AWR1642移植到 AWR1843、但之前的工程师在之前编写的许多主题已经完成了类似的移植、这可能会有所帮助。 例如：  

• https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/957235/awr1843boost-srr-lab-gui-satured-by-excesive-cloud-of-points---usrr-profile
• https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1356113/awr1843boost-awr1843boost/5185849?tisearch=e2e-sitesearch&keymatch=AWR1843BOOST%20SRR%20demo%20lab%202#5185849

如果演示已正确移植、但您仍然看到传感器位置/速度与数据之间的不匹配、则.cfg 文件中可能存在偏移。 您可以参考感应估算器(https://dev.ti.com/gallery/view/mmwave/mmWaveSensingEstimator/ver/2.4.0/)来检查和配置配置配置。

谢谢！

Jin

你好

感谢您的答复。  我将托盘以修改 profilecfg 和 chirpCfg、但传感器不提供数据。

谢谢！

尊敬的 Sriram：

您还可以参阅此常见问题解答、了解如何在 AWR1843上运行 AWR1642代码、该常见问题解答链接在上面的 E2E 主题中： https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/965635/faq-awr1843-running-awr1642-code-on-awr1843

除了修改 AWR1843上其他 Tx 的线性调频脉冲配置、还请按照常见问题解答中所述更新 DSS 和 MSS 的.projectspec。 演示的其余部分应该不需要更改。  

您可以在雷达工具箱的占位检测实验中找到这种移植的示例-可以扩散配置文件和.projectspec 文件、以显示所做的确切更改。

谢谢！

Jin

您好！

the.projectspecs 文件中必须更改的内容以及如何更新

您好！

我将进行 MRR 演示,但它没有检测到静态对象,并且 USRR 数据偏移到一边,就像这样:对象在传感器中直走两米,但绘图仪在左侧或右侧显示一个蓝点几米。

您好！

谢谢您的重播。 我将利用 AWR1843中的 SRR 实验室、并将更改 AWR1843中的代码 TX 天线。 我将在 TX1和 TX3上启用、对吗？

您好！

SRR 项目基本上满足了我们的需求;唯一需要改进的是 X 的速度和方向数据不匹配。我仍然会问 SRR 实验室解决方案。

MRR 实验我将禁用基于距离的修剪它正在工作、但它也可以检测错误警报和接地仪表组。

此外、MRR 实验室使用硬编码校准。 因此、请说明如何应用校准。

请给出解决方案。

EVM 校准是否需要 DCA1000？
