XL-MaxSonar^®- EZ/AE™ Series

Real-time Noise Rejection

While the XL-MaxSonar^®is designed to operate in the presence of noise, best operation is obtained when noise strength is

low and desired signal strength is high. Hence, the user is encouraged to mount the sensor in such a way that minimizes

outside acoustic noise pickup. In addition, keep the DC power to the sensor free of noise. This will let the sensor deal

with noise issues outside of the users direct control (in general, the sensor will still function well even if these things are

ignored). Users are encouraged to test the sensor in their application to verify usability.

For every ranging cycle, individual filtering for that specific cycle is applied. In general, noise from regularly occurring

periodic noise sources such as motors, fans, vibration, etc., will not falsely be detected as an object. This holds true even if

the periodic noise increases or decreases (such as might occur in engine throttling or an increase/decrease of wind

movement over the sensor). Even so, it is possible for sharp non-periodic noise sources to cause false target detection. In

addition, *(because of dynamic range and signal to noise physics,) as the noise level increases, at first only small

targets might be missed, but if noise increases to very high levels, it is likely that even large targets will be missed.

*In high noise environments, if needed, use 5V power to keep acoustic signal power high. In addition, a high acoustic noise

environment may use some of the dynamic range of the sensor, so consider a part with less gain such as the MB1220/MB1320

MB1230/MB1330 or MB1240/MB1340. For applications with large targets, consider a part with ultra clutter rejection like the

MB7369.
