IWR6843: achieve max distance of above 1Km

Tool/software:

Hi,

I was wondering if we can use any of your Radar chips in order to detect a 0dBsm (1sqm) target from a distance of more than 1Km?

can we use long frames (i.e. long integration time), 

or can you offer any design in which external power amplifiers are used?

thanks

    Hello, 

    Can you share a bit more info about the application you are targeting? There are regulatory restrictions to using higher Tx output power based on frequency band and type of application targeted.

    To even come close to achieving 1Km detection range with our devices you would likely need several chips cascaded together and possibly with a custom high gain antenna as well. I'm hesitant to say it's not possible, but it is highly unlikely, especially considering the target size of 1m2. 

    Best Regards,

    Josh
