Marine Radar Object Classification via Tidal Velocity Vector Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current object detection systems in marine environments are inefficient and laborious, particularly in determining whether objects are stationary or moving, especially when objects lack identification hardware, and they struggle to accurately classify objects based on their velocity relative to tidal currents.
Innovation Solution
An object detection apparatus that uses processing circuitry to detect objects in a water body via radar, calculate velocity vectors for both objects and tidal currents, and classify objects as stationary, moving with the tidal current, or moving independently, by comparing these vectors and generating similarity values to notify users through visual displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual origin mark insertion method is used to determine positional relationship, then object classification capability is provided, but operational efficiency deteriorates and time consumption increases
Solution Approach 1:
The system automatically performs object classification by comparing detected object positions with pre-stored origin mark positions, eliminating the need for manual origin mark insertion. The processor autonomously determines whether objects are stationary or moving based on positional relationship changes, making the system self-sufficient in classification tasks.
Solution Approach 2:
The patent replaces the manual mechanical operation of inserting origin marks with an automated electronic system. The processor electronically compares object positions with stored reference positions, substituting manual labor with automated computational processes that significantly improve operational efficiency.
2Loss of time
If no origin mark is inserted, then operational time is reduced, but object classification accuracy deteriorates
Solution Approach 1:
The system performs preliminary action by pre-storing origin mark positions in memory before actual object detection begins. This allows the processor to immediately compare detected object positions with the pre-prepared reference data, enabling rapid and accurate classification without manual intervention during the detection process.
3Device complexity
If radar detection is performed without automated velocity analysis, then detection simplicity is maintained, but object classification precision deteriorates
Solution Approach 1:
The patent applies parameter changes by analyzing the velocity parameter of detected objects. The processor calculates velocity vectors by comparing positional changes over time and classifies objects based on velocity thresholds, transforming a simple detection system into one with enhanced classification precision through quantitative parameter analysis.

AI summary
An apparatus for nautical tracking, where the apparatus detects at least one object. The apparatus further determines radar information associated with the at least one object, and calculates a first velocity vector associated with the at least one object. The apparatus further determines information associated with a tidal current of the water body, and calculates a second velocity vector based on the information associated with the tidal current. The apparatus further compares the first velocity vector and the second velocity vector in order to classify an object of the at least one object as a target, and further notifies a user of the target.
