Solution Overview
Problem
Existing radar target simulators require expertise to operate effectively, making them difficult for users with less experience to define and simulate radar targets for testing radar devices.
Innovation Solution
A radar target simulator with a graphical user interface providing a two-dimensional representation and input module allows users to intuitively define targets by positioning symbols within the interface, setting properties such as radar cross section, distance, and velocity, without needing to input specific values, using a WYSIWYG-editor for easy target scenario creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If column-like lists and dropdown menus are used to define target properties, then the simulator can simulate multiple targets with defined properties, but the operation becomes complex and requires expert knowledge
Solution Approach 1:
The patent transforms the traditional one-dimensional property input (column lists with individual parameters) into a two-dimensional spatial representation where targets are positioned on a display screen. Users define targets by dragging symbols to positions on the screen, where the x-coordinate represents range and the y-coordinate represents velocity. This dimensional transformation allows multiple target properties to be defined simultaneously through spatial positioning rather than sequential parameter entry, significantly reducing operational complexity while maintaining full simulation capability
Solution Approach 2:
The patent creates a visual copy of the radar measurement overview on the display screen, where target symbols represent actual radar targets. Instead of requiring users to input abstract numerical values for each property, the system provides visual symbols that users can manipulate directly on the screen. The symbol's position, size, and visual characteristics correspond to target properties, allowing users to define targets through intuitive visual manipulation rather than expert-level parameter specification
2Manufacturing precision
If detailed parameter input is required for each target property, then accurate target definition is achieved, but the time and complexity of operation increases
Solution Approach 1:
The system pre-configures the display screen with a coordinate system where the x-axis represents range and the y-axis represents velocity, along with target symbols that have predefined visual characteristics corresponding to different target types. When a user drags a symbol to a position on the screen, the system automatically extracts the coordinates and converts them into the corresponding radar target properties. This preliminary setup eliminates the need for users to manually input each parameter, as the position information is automatically captured and converted into accurate target definitions, significantly reducing setup time while maintaining precision
Solution Approach 2:
The patent replaces the manual mechanical process of entering each parameter value through keyboard input with an automated coordinate extraction system. The display screen captures the positional coordinates of dragged symbols, and the processing circuit automatically converts these spatial coordinates into radar target properties (range from x-coordinate, velocity from y-coordinate). This substitution of manual parameter entry with automated coordinate-based definition reduces both time and potential for human error, achieving accurate target definition through visual manipulation rather than detailed numerical input
Data Source
AI summary
A radar target simulator for simulating a radar target is disclosed. The radar target simulator comprises a display module and an input module via which a user of the radar target simulator is enabled to define a target to be simulated. The radar target simulator also comprises a processing module that is connected with the display module and the input module in a signal transmitting manner. The display module and the processing module together provide a graphical user interface for the user of the radar target simulator. The graphical user interface provides a two-dimensional representation of an at least two-dimensional space. The processing module receives at least one input signal from the input module based on an input of the user. The input of the user is associated with input coordinates in the two-dimensional representation. The processing module processes the at least one input signal, thereby generating a symbol of the target defined. The display module illustrates the symbol generated in the two-dimensional representation provided by the graphical user interface.
