Original question:
Hi,
Amanda's reply said that 'The increased on-board memory of the 1642 enables higher range and resolution measurement.'
Could you please explain it in details? Higher range - longer range? What is the maximal range now? Higher resolution - is this finer resolution? What is resolution now?
Could you please list the maximal range and resolution of both IWR1443 and IWR1642 here?
Thank you.
Best regards,
Jiadi
Hello Jiadi,
Please see the sensing estimator for a comparison between the sensing capabilities of the devices:
For more information please refer to this application note specifically, section 2.1.1 and 2.1.2 for Maximum Range and Resolution: 
Note that the IWR1642 supports 5MHz IF Bandwidth and a sampling rate of 12.5MSPS while the IWR1443 supports 15MHz IF Bandwidth and a sampling rate of 37.5MSPS. Therefore, purely from a radar front end persepctive the IWR1443 supports a higher range - note that max range is dependent on other parameters such as the characteristics of object to be sensed.
Range resolution is determined by the sweep bandwidth used, both devices support up to 4 GHz sweep bandwidth, which translates to ~4cm range resolution.
The IWR1642 has a DSP and additional memory which can enable more complex detection algorithms or higher level algorithms such as tracking.
