Electronic Jamming Signal Detection for Continuous Threat Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing EW systems face challenges in efficiently responding to multiple broadband threat signals without stopping the search for threat signals in other frequency ranges or stopping the transmission of jamming signals, leading to delayed response times when different frequency ranges are encountered.
Innovation Solution
An electronic apparatus with a signal detecting part that identifies threat signals in the frequency range where jamming is performed, allowing continuous search and analysis of threat signals across different frequency bands, and a controller that adjusts jamming resources based on threat detection, ensuring efficient and timely response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the EW system uses the look-through technique to determine jamming effectiveness by temporarily stopping jamming signal transmission, then the effectiveness of jamming can be assessed, but the response time to threat signals is delayed and the search for threat signals in other frequency ranges is interrupted
Solution Approach 1:
The patent divides the signal processing function into two independent parts: a signal analyzer that continuously searches for threat signals across all frequency ranges, and a signal detector that specifically monitors the jamming frequency range to assess effectiveness. This segmentation allows both functions to operate simultaneously without interfering with each other, resolving the contradiction between assessing jamming effectiveness and maintaining rapid response capability.
Solution Approach 2:
The patent introduces a signal detector as an intermediary component that monitors the jamming frequency range without requiring interruption of jamming signal transmission. This intermediary enables effectiveness assessment to be performed continuously in parallel with the jamming operation, eliminating the need to stop jamming signals for assessment purposes and thus maintaining rapid response time.
2Measurement precision
If the EW system stops transmitting jamming signals to assess effectiveness, then the threat signal can be detected in the jamming frequency range, but the transmission of jamming signals is interrupted and response time is delayed
Solution Approach 1:
The patent segments the detection function into two independent components: a signal analyzer for continuous threat signal search across all frequencies, and a signal detector for specific monitoring of the jamming frequency range. This allows threat signal detection accuracy to be maintained without interrupting jamming signal transmission, as the signal detector can continuously monitor effectiveness while the jamming operation continues uninterrupted.
Solution Approach 2:
The patent enables continuous monitoring of jamming effectiveness through the signal detector that operates simultaneously with the jamming signal transmission. This continuity allows the system to maintain both accurate threat signal detection and uninterrupted jamming operation, eliminating the need to stop transmission for assessment purposes.
3Reliability
If the EW system re-searches the jamming frequency range after temporarily stopping jamming, then jamming effectiveness can be determined, but the response time to threats in other frequency ranges is delayed
Solution Approach 1:
The patent segments the signal analysis function into two independent parallel processes: the signal analyzer continuously searches all frequency ranges including the jamming frequency range, and the signal detector specifically monitors the jamming frequency range for effectiveness assessment. This segmentation enables simultaneous operation without interruption, allowing the system to determine jamming effectiveness while maintaining continuous search capability in other frequency ranges, thus eliminating response time delays.
