Do propellers interfere with obstacle avoidance sonar sensor?

Hello, i want to know how much interference dose propellers produce when they come in the path of the obstacle avoidance sensor beam or they don’t have any effect on there performs.

I will be using the Maxbotix MB1240 sornar sensor.

yes they do, a lot. more chars

This is the design i am have been working on the black dot at the centre of the red circle is the sonar sensor and the blue line can be assumed as the propeller and the red cicrles around the sensor as spreading waves. How much interference this configuration can produce will there be any way we filter out the interference?
