Maxbotix HRXL-MaxSonar-WRM Weather Resistant Ultrasonic Range Finder

The Maxbotix HRXL-MaxSonar-WRM Weather Resistant Ultrasonic Range Finder are equipped with filtering firmware which allows the sensor to ignore smaller targets and noise, and still report the target that gives the largest acoustic return. This gives users the flexibility to consistently range larger targets in the presence of clutter and noise. If the largest target is removed from the field of view, the HRXL-MaxSonar-WRM will switch to the target that gives the next largest detectable return. The Most-Likely filter is designed to report the distance to the largest acoustic return while ignoring smaller targets. When targets are of similar amplitude reflections, preference is given to the closest target.
