Hello,

I am having a problem with measurement accuracy. Despite using a high slope frequency (241 MHz/microsecond), I notice in the 1D FTT that the measurement is incorrect by +6 cm compared to the actual distance. How can I correct this error?

Best regards,

Hi,

This is called the "range bias" Usually it is measured and after that it is just subtracted from the detected range.

Thank you

Hello,

How can I delete it automatically and get an exact distance?

The range bias is usually constant. So you just need to subtract it from your measurement

thank you

Hello,

I notice that the distance varies between 6 cm and 7 cm of range bias. Which parameter guarantees a fixed range bias? The frame number or something else ?

Thank you for helping,

Best regards,

Yes, usually there may be a small variation. You can perform an average if needed
