Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional radar systems are deployed to achieve surveillance coverage, then detection capability in adverse weather is improved, but electromagnetic interference and device complexity increase
Solution Approach 1:
The radar system is divided into multiple independent radar units, each operating autonomously with its own transmitter and receiver. These segmented units can be distributed across different locations and frequency bands, reducing mutual electromagnetic interference while maintaining comprehensive surveillance coverage
Solution Approach 2:
Each radar unit operates at different frequency bands or with different modulation parameters, allowing simultaneous operation without significant interference. The system dynamically adjusts transmission parameters to optimize detection while minimizing electromagnetic conflict between multiple radar units
2Area of stationary object
If multiple radar units are deployed to improve coverage, then surveillance area is expanded, but signal correlation and system integration become more difficult
Solution Approach 1:
The system pre-establishes synchronization protocols and coordinate transformation relationships between radar units before operation. Each unit is pre-configured with its position and orientation data, enabling seamless signal correlation and integrated target tracking across the distributed network
Solution Approach 2:
A central control unit or communication protocol acts as an intermediary to coordinate the distributed radar units. This mediator manages signal timing, frequency synchronization, and data fusion, simplifying the integration complexity of multiple radar units into a unified surveillance system
3Reliability
If traditional radar systems are used for surveillance, then detection in bad weather is achieved, but deployment flexibility and adaptability are limited
Solution Approach 1:
The radar system is modularized into independent units that can be easily deployed and reconfigured. Each segment can be independently installed on different structures (buildings, vehicles, towers) and adapted to various geometries, providing deployment flexibility while maintaining all-weather detection capability
Solution Approach 2:
The radar units are designed with universal mounting configurations and standardized interfaces, allowing them to be deployed on diverse structures and adapted to different surveillance requirements. The same basic unit can serve multiple functions depending on its location and configuration

AI summary
Surveillance system for detecting the position, movement, nature of one or more objects and even communicate with it, that is adaptive to any extent and suitable for any mobile or fixed structure and even for persons, because of its flexible open architecture, which is fully modular to develop self-contained compact radar devices of special performances when working either autonomously, like conventional video-cameras nevertheless operating also with microwaves and therefore called microwave-cameras or radar-cameras, or jointly to form more complex interactive systems.
