Description

The TIDEP-01024 reference design demonstrates the use of the AWR1843AOP for 3D space obstacle detection applications. The AWR1843AOP is a 76-81GHz single-chip, frequency modulated continuous wave (FMCW) mmWave sensor with an integrated antenna. The sensor also has integrated DSP, MCU and a hardware accelerator for FFT processing.

This design provides a reference software-processing chain, which runs on the C674x DSP, enabling the detection of several objects in both azimuth as well as elevation planes, with a field of view (FOV) of ±70 degrees in azimuth and ±70 degrees in elevation. A GUI is provided to visualize the object detection.
