user50518: I am planning to to use ultrasonic sensors mounted on a drone for obstacle avoidance. I am not sure if the sensors would be capable of detecting a Net Like obstacle in its path.

user50170: There is always a chance of picking up the net for a split second, but most likely, you will never accurately detect the net with this type of sensor. There is too little to detect.
