    Hello Yousuke, 

    The picture demonstrated in the user guide (which you have showed above) is for a "Test Source" object which is a simulated object at a programmed range (5m in this case).

    Your measurement scenario is a real life scenario with a few objects around. The reflections from the neighboring objects may not be strong enough to get a clear range peak. You can use a high RCS object or a strong corner reflector and keep it at a fixed distance w.r.t the sensor to observe and make sense of the captured data. 

    Hope this makes sense. 

    Regards,

    Ishita
