Other Parts Discussed in Thread: TIDEP-0090
Hello,
I have a question about 'TI Designs: TIDEP-0090; Traffic Monitoring Object Detection and Tracking Reference Design Using Single-Chip mmWave Radar Sensor' document.
The above table is a copy from the mentioned document.
For Medium-Range MIMO example, using the provided parameters, I think the maximum range should be 38.94m instead of 70m.
My calculation is shown as follows:
maximum beat frequency = 1/2 * ADC sampling rate; (from Nyquist criterion)
maximum range = speed of light * maximum beat frequency * sweep duration / (2 * sweep bandwidth);
then I got maximum range equals to 38.94m.
My question is: how can we get maximum range equals to 70m with the provided parameters?
Thanks in advance.
Regards,
Jiadi
