Other Parts Discussed in Thread: AWR1843BOOST

Good afternoon! Could you tell me what maximum range and maximum speed of objects can be processed by this chip? I want to use this chip to determine the speed of vehicles

    Hi,

    The maximum range and speed that can detected depends not only on the chip but also on the PCB antenna design.

    We have developed a demo using the AWR1843BOOST EVM to show maximum performance.

    This EVM has a generic antenna and does not achieve the best performance of the chip.

    With this antenna we can achieve ~150-160m vehicle detection at 144km/h.

    Please see the demo material on the TI Resource Explorer: dev/ti.com

    The demo is provided in the mmWave Sensors - Automotive Toolbox folder

    Please download the entire zip file. You will be able to find the demo in

    mmwave_automotive_toolbox_2_9_1\labs\lab0007_medium_range_radar

    Thank you

    Cesar
