We currently doing a circuit to drive a 2MHz ultrasonic sensor. The results we got is inconsistent echo signals, even we put a aluminium plate 50cm in front of it. Is anyone have this exprience before? I also looking for some useful resources in designing the circuit. Please leave your opinions here. Thanks

2 MHz is quite high for an ultrasonic sensor. Can you post a schematic to give us a better feel for the circuit you are using?

Which type of transducer you are using ?
I am using electrostatic transducer & I am getting good results.
If possible let me have look at the circuit you are using.
If you are using electrostatic transducer, I will send you my circuit.
