normally we get that characterization only from datasheet of the sensor. not so sure what is the exact and accurate way for doing that, mayb u can get some info from searching and share with us?
however, easy way to do that is just doing plot of amplitude of the received ultrasound on every degree of angle centered at the US transmiter. just use an osccilloscope to read out the amplitude on receiver side.
thanks®ards,
