Part Number: IWR6843ISK
Other Parts Discussed in Thread: IWR6843

I want to know the specifications of IWR6843 Traffic monitoring LAB.

(Detection distance, Detection speed range, Speed Accuracy, Distance accuracy, Angular Resolution, Number of simultaneous track tracks)

Where can we find this spec?

    Hello,

    The traffic monitoring lab is a port of the 16xx lab and thus users should review the TI Design for detailed test results and specifications: http://www.ti.com/tool/TIDEP-0090

    It looks like that 195(65km/h*3 chirps) km/ is the maximum speed that can be measured.

    The followings are the specification that we would like to meet with TI mmwave 6843.

    1. we would like to detect velocity range up to  250km/h,

    2.simultaneous detection of 64 to 128 cars

    Are there any way to meet this specification?

    BR,

    Hello,

    The maximum speed is depndent on the chirp configuration. This can be redesigned to increase the maximum speed with other tradeoff considerations. The Sensing Estimator tool enables users to input their detection requirements and determine whether the sensor can achieve the desired specs: http://www.ti.com/mmWaveSensingEstimator

    For the number of vehicles 64-128 is a wide range. This range of vehicles has not been tested. It is also important to consider the range and density of vehicles. Please refer to the gtrack documentation to understand the memory requirements. Currently the demo is only configured to allocate memory for 20 tracked objects. To increase the number of tracked objects you will need to modify the memory. However this will not change whether the sensor is sensitive to separate out the vehicles if they are closely packed.
