IWR1443: To apply the mmWave use in 3D space detection question

Curtis Wang

Part Number: IWR1443

Hi,

    I have several questions about the mmWave applying in 3D space detecion, please help to provide solve methods, thanks a lot~!!   

Q1：The mmWave When using the function of scanning the surface, whether with the same as the ultrasound can produce the depth of the image information ?

Q2：How to use mmWave to scan and get 3D space information?

        EX：if used the IWR 1443 that have three TX antennas could we get information of 3D space? or could we use two modules or more combines to get 3D space information ?

Q3：Based on Q2, if the mmWave can get 3D space information, would you provide the height and the maximum angle of the sensor's 3D detection ability ?

BR,

    Hi Curtis,

    It sounds like you would like to use the device to produce a contour map of a surface? I have not seen the device used in this way, so I can't say off-hand if it's possible. I will check internally. Typically, the device analyzes radar returns performing FFTs on the ADC samples, so a list of objects is produced with x-y-z coordinates for each. For contour mapping, I believe you need to find the range to each point in the field of view, similar to ray tracing.
