Part Number: AWR1443BOOST
Other Parts Discussed in Thread: DCA1000EVM, AWR1443
Hi,
Recently, I use AWR1443+DCA1000eVM for range/distance measurement with the raw radar data captured by mmWave Studio. The distance is calculated with beat frequency with FFT and the target is static. The transmitted bandwidth is used for the bandwidth regarding to ADC sampling time (i.e., the bandwidth B is calculated correctly).
The experimental results show that there is alway a approximately fixed error (larger than the truth about 6-8 cm). I have try 0.5 G, 1G, 2G and 2.5 G bandwidth.
Therefore, I wonder what is the reason about the error. Is there a fixed time delay on the hardware? We need to calibrate and compensate for this error?
Thank you very much for your instruction.
Regards,
Yuyong
