IWR6843ISK-ODS: overlapping sensor f.o.v / multiple sensors in room

Part Number: IWR6843ISK-ODS

. I am currently looking to deploy multiple mm-wave sensors within one room to increase the coverage area. Due to this set up, there are overlapping fields of view between the two sensors.

Both sensors have been processed so that their output in one frame is a single point representing a person [x,y,z]. I would like to know how to handle this information when 2 sensors record the same person in a single frame, producing two different [x,y,z] outputs based on their local coordinate systems.

Have you dealt with this issue before? Any help or guidance you could give me would be greatly appreciated.

    Hello,

    Each radar system will only output the object coordinates relative to the sensor location.  You will need to use a host processor or some central unit that knows the relational position of the two radar systems so you can map the 2 coordinate systems of each radar onto a common room coordinate. 

    Or, you can modify the software on the device to accept some room position coordinate as an input. The the device can translate the output pointcloud by this value to make the output match a common room coordinate system.

    Either way this will be higher level application code, so the there may be many solutions.
