Echo Image Display Data Rate Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radar devices only enlarge normal echo images without increasing their resolution, resulting in the same information amount as the original image, which limits the detail and accuracy of target object detection.
Innovation Solution
An echo image display device that changes the data rate of a predetermined area on the display by adjusting the number of electromagnetic wave discharges, sampling rate of echo signals, or interpolating image data, allowing for higher resolution in specific areas, thereby increasing the information amount displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the normal echo image is simply enlarged, then the display size is increased, but the resolution level remains unchanged and the information amount is not increased
Solution Approach 1:
The patent applies local quality by differentiating the data amount rate across different display areas. The predetermined area (where target objects exist) uses a higher data amount rate with more electromagnetic wave discharges and higher sampling rates, while other areas use a lower data amount rate. This resolves the contradiction by providing high resolution locally in the predetermined area while maintaining overall large display coverage.
2Measurement precision
If the data amount rate is increased for the entire display area, then the resolution is improved, but the device load increases
Solution Approach 1:
The patent segments the display area into a predetermined area (where target objects exist) and other areas. By applying different data amount rates to these segments - higher rate for the predetermined area and lower rate for other areas - the system achieves high resolution where needed while reducing overall device load through selective processing.
3Loss of information
If the number of electromagnetic wave discharges is increased, then the information amount is increased, but the energy consumption increases
Solution Approach 1:
The patent applies local quality by concentrating electromagnetic wave discharges in the predetermined area where target objects exist. The number of discharges is increased specifically in this region to capture more information, while other areas use fewer discharges. This resolves the contradiction by maximizing information gathering locally where needed while minimizing overall energy consumption.

Function Achieved in This Case
This approach enhances the resolution and information content of echo images, improving detection accuracy and reducing device load by focusing on specific areas rather than the entire display, allowing for more precise identification of target objects.
