IWR1843: Sensors forum

Part Number: IWR1843

Hi, I read the article written by Muhammet Emin YANIK about using IWR1843 and DCA1000 for track synchronization for SAR. But I don't know how to synchronize the radar with the rails generated by FUYU, I can only measure and overlay horizontally row by row, which reduces my work efficiency a lot, can you please provide a manual for the parallel connection of the millimeter wave development board and the external rails so as to achieve synchronization?

Hello. Thanks for the question.

Please refer to the following paper for more details about the radar-rail synchronization:

https://ieeexplore.ieee.org/document/9136646

In 'Section IV. Synchronization Between the Scanner and Radar', two synchronization approaches are discussed. You can either use the SW trigger feature of the radar to control both rail and radar from a common MATLAB application. Or, you can use the HW trigger feature of the radar to trigger the frames at every precise position of the scanner using an embedded real-time solution.

There is a MATLAB toolbox that you can utilize for this purpose.
