Solution Overview
Problem
Existing sonar systems face challenges in providing a simplified visualization of target parameters while indicating their reliability, often overwhelming operators with numerous diagrams and lacking clear information on the accuracy of optimized solutions.
Innovation Solution
A method that calculates quality specifications for target trajectories based on differences between assumed and measured bearing angles, using weighting factors to promote convergence, and represents these specifications graphically or numerically in a single solution space, highlighting the best solution and its reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire solution space is shown for each target parameter in two or three-dimensional diagrams on a separate display, then the reliability information is provided, but the display means and number of individual diagrams overload the operator
Solution Approach 1:
The patent combines multiple separate display diagrams into a single integrated solution space representation. Instead of showing target parameters in separate two or three-dimensional diagrams, the invention merges them into one comprehensive display that presents the entire solution space with quality measures, thereby reducing operational complexity while maintaining reliability information.
Solution Approach 2:
The single solution space display serves multiple functions simultaneously: it displays target parameter ranges, presents quality measures for reliability assessment, and provides a unified overview of all possible solutions. This multi-functional approach eliminates the need for multiple separate diagrams while maintaining comprehensive information presentation.
2Loss of information
If multiple separate display diagrams are used to show solution spaces for target parameters, then comprehensive information is provided, but the operator is overloaded with additional display means
Solution Approach 1:
The invention merges the information from multiple separate display diagrams into a single integrated solution space representation. This consolidation maintains comprehensive information about target parameters and quality measures while eliminating the operational burden of managing multiple separate displays.
Solution Approach 2:
Within the single solution space display, the patent segments information by presenting different target parameter ranges and quality measures in an organized, structured manner. This segmentation allows comprehensive information to be displayed systematically without creating visual clutter or operator overload.

AI summary
The invention relates to a method for determining and representing possible target parameters, in particular of a target distance R, a target course C and/or a target speed V of a target. For this purpose, a plurality of different target tracks Z(i, j) having associated quality information are determined from the possible solutions during each processing cycle of an optimization method that is applied. Future target positions (25), which together with the quality information form a future expectation area (42), are determined for said target tracks Z(i, j). In addition, a distance solution space (34) and a vector indicating the best solution Zbest is determined from the possible solutions. The future expectation area (42), the distance solution space (34) and/or the best solution Zbest can then be represented in a single solution space in the form of a position representation on a display device (27).
