IWR6843 : hello my name is KIm donghwan I have a questions about mmwave sensor IWR6843

Part Number: IWR6843
Other Parts Discussed in Thread: TIDEP-01000

hello my mane is KIM donghwan and i am student of  kyonggi university

while i am studying about decresing 'energy coumsuption of elevator by sensors'

i got to know about presentation of 'mmwave sensors improve artifical intelligence algorithms for more efficient us of elevators '   by  GUSTAVO MARTINEZ the engineer of TI

mmwave sensors 

i have questions about mmwave sensors

1.in TIDEP-01000 there are 'IWR6843 ' the chip using mmwave 

  as i was studying i found that the 'IWR6843'  can people counting and tracking

 what is the priciple of people counting and tracking

2.as i saw the 'IWR 6843'  can Distinguish people, non- people 

what is the principle of that?

3.i wanna know about fatures of mmwave sensor using 'IWR 6843'

how much is that sensor?

how much the mmwave sensor use  eletric power by hour?

sensor's visual field

ditection range

resolution

detection velocity

    Hi Kim,

    I've asked an expert to look into this and we should have an answer for you later this week.

     

    Cheers,

    Hi Kim,

    1. Please see the TI Design for more details on the People Counting software. Essentially, the DSP processes raw radar data to create a point cloud, then the Cortex R4F runs a tracker that tries to distinguish clusters in the point cloud, and track them.
    2. The classifier runs on tracker data, and makes a determination based on the micro-doppler characteristics of the demo. See this for more details.
    3. IWR6843
      1. FOV - depends on antenna, ISK has 120 degree Azimuth and 40 degree elevation FOV
      2. Range - depends on antenna and detection object - human with ISK max range is about 100 meters.
      3. Resolution - depends on antenna and chirp configuration, see this doc for more details.
      4. Detection Velocity - see answer to C
      5. Cost - cannot give you a price quote on this forum
      6. Power - depends on configuration, expect 1 - 2 Watts

    Regards,

    Justin
