Abstract
An airborne sonar collision avoidance system is disclosed. The system compensates for changes in temperature in real time to provide more accurate sonar detection. In addition, the sensors are arranged in a communications network that allows for the sensors to be programmed at run time, thus providing the ability to relocate the sensors without having to pre-program the sensors before the sensors are installed onto a different location.
Claims9
An ultrasonic sensor, comprising:
- a transducer for transmitting and receiving sound waves;
- a drive circuit connected to the transducer for driving the transducer to produce sound waves according to predetermined sound pressure level;
- and
- a microcontroller connected to the drive circuit for directing the drive circuit to produce a predetermined amount of voltage, the amount of voltage determined as a function of environment temperature and the predetermined amount of voltage directly related to the predetermined sound pressure level.
