Solution Overview
Problem
Current methods for testing radio follower jammer robustness are time-consuming and lack reproducibility, making it difficult to reliably determine and compare the robustness of radios under test.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual testing methods are used to test follower jammer robustness, then the test can be performed with simple equipment, but the testing process becomes time-consuming and results are not reproducible
Solution Approach 1:
The system records the original radio communication signal beforehand and stores it for later use. This preliminary recording action allows the same signal to be reused multiple times in different test scenarios, ensuring reproducibility while eliminating the need to manually recreate identical test conditions each time.
Solution Approach 2:
The system creates a copy of the original radio communication signal by generating a delayed signal that replicates the characteristics of the original. This copied signal can be precisely reproduced across multiple tests, ensuring consistent and reproducible results without manual intervention.
2Manufacturing precision
If manual follower jammer generation is used, then equipment complexity is reduced, but the ability to perform controlled and defined testing is limited
Solution Approach 1:
The signal generator acts as an intermediary device that receives the original signal, adds a controlled delayed signal, and outputs the composite testing signal. This intermediary component enables precise control over the jamming signal characteristics while maintaining a relatively simple overall system architecture.
Solution Approach 2:
The system controls the delayed signal by adjusting specific parameters such as delay time and signal amplitude. By changing these parameters, the system can precisely control the follower jammer characteristics without requiring complex manual adjustment procedures.
3Productivity
If multiple radios are tested simultaneously, then productivity increases, but ensuring consistent test conditions across all radios becomes difficult without automated control
Solution Approach 1:
The test system is designed with universal components that can test multiple radios using the same signal processing chain. The signal analyzer and signal generator can serve multiple radios simultaneously or sequentially with the same configured delayed signal, ensuring consistent test conditions across all devices while maintaining high productivity.
