Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic powder is mixed with a binder to form a radio wave absorber, then radio wave absorption performance is improved, but mechanical durability deteriorates
Solution Approach 1:
The invention uses a composite material system consisting of substitution-type hexagonal ferrite powder (with specific crystal structure and composition) combined with a polyamide binder. This composite achieves both excellent radio wave absorption performance and mechanical durability through the synergistic effect of the magnetic powder's electromagnetic properties and the polyamide's mechanical strength and adhesion.
2Measurement precision
If a radio wave absorber is installed on the radar to improve recognition accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The invention optimizes specific parameters of the radio wave absorber including the crystal structure composition (substitution-type hexagonal ferrite with specific atomic ratios), particle size distribution, binder content, and manufacturing conditions. By precisely controlling these parameters, the absorber achieves superior radio wave absorption performance that enhances radar recognition accuracy without requiring complex system modifications.
