AWR1443: Or AWR 1642, ranging out to 125m using onboard processing

Part Number: AWR1443
Other Parts Discussed in Thread: AWR1243, AWR1642,

I am comparing the three AWR mmWave chips and am looking to detect vehicles up to 125m and ideally further under good weather conditions. 

To my understanding the AWR1243 is the best option for this given its wider intermediate frequency bandwidth of 15MHz vs. 5MHz on the other two chips. However, I would like to avoid the use of an FPGA for cost reasons since this is for an academic capstone project and cannot buy the TDA3X Evaluation Module.

Is there a way that I can get beyond or at least close to 125m using either the AWR1443 or AWR1642 despite the smaller IF range?

  • Greg,

    I would recommend using the AWR1642. The onboard DSP can provide additional levels of FFT processing that can be used to analyze chirps.

    Using our SRR demo found on TI's Resource Explorer, we have a chirp designed to detect objects at up to 80 meters.

    You can also you the mmWave Sensing Estimator Tool to create your own chirp based on your specific criterion.
