AI Technical Summary
Technical Problem
Existing sonar systems struggle to accurately detect the position of targets when multiple targets are close to each other or have complex shapes.
Method used
A processing device that includes a memory unit to store ranging values and past ranging values, along with a processing unit to determine the validity of these values based on sensor movement information, thereby improving target position accuracy by filtering out errors in distance measurements.
Benefits of technology
This approach suppresses a decrease in detection accuracy by effectively handling multiple targets and complex shapes, enhancing the precision of target positioning.

Abstract
To provide a processor capable of accurately detecting the target position even when multiple targets exist in proximity, or even when there are targets with complex shapes.SOLUTION: A processor in a disclosed embodiment includes: a storage unit that stores the measured distance value that indicates the distance to the target measured by the sensor at the first time point and a past measured distance value that indicates the distance to the target measured by the sensor at one or more points in time before the first point in time; and a processing unit that determines whether the measured distance value is valid or invalid based on the measured distance value, the past measured distance value, and the sensor movement information.SELECTED DRAWING: Figure 3
