    I have two x4m03 modules now, and I want to build a two-radar system which these two radars separately measure their own radar frame. No beam forming is needed. How can I configure the module?

    Thanks for your help

    Hi Wang,

    You can just use X4 based radars in the same space. It is usually no problem, but I want to give some background information.

    Other X4 radars transmitting in the same frequency area, will give in-band interference. Regulations ensure that the amount of energy is low. X4 has several noise reduction techniques, including a pseudo-random number generator, randomizing the phase of the transmitted pulses. This will give each radar a unique signature, the interference from other X4 radars will be attenuated dramatically.

    Thanks Charlie, I have tried and they work very well.

    Hi Charlie,
    I want to ask how to make multiple radar modules start running at the same time, so that their received signals are synchronized in time.
