Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a radar system is designed to detect high-speed targets at close range, then detection speed and accuracy are improved, but the system complexity and space requirements increase
Solution Approach 1:
The radar system is divided into multiple independent detection and tracking sectors, each with its own transmit and receive antenna units. This segmentation allows the system to cover a wide angular range while maintaining simple, modular sector units that can be independently configured and maintained.
2Area of stationary object
If multiple detection and tracking sectors are used to cover a wide area, then detection coverage is improved, but maintaining continuous tracking across sectors becomes complex
Solution Approach 1:
The controller receives signals from multiple detection and tracking sectors and uses feedback mechanisms to continuously track targets as they move between sectors. The system processes signals from adjacent sectors and maintains target information continuity through coordinated control based on received signals.
3Volume of moving object
If integrated antenna units are used for each sector, then system compactness is improved, but manufacturing precision requirements increase
Solution Approach 1:
The transmit antenna unit and receive antenna unit are integrally formed as a single antenna unit for each detection and tracking sector. This merging reduces the overall system volume and simplifies the structure by eliminating the need for separate mounting and alignment of transmit and receive antennas.
4Loss of time
If the radar system is designed for rapid detection of high-speed targets, then response time is improved, but the system requires more advanced signal processing capabilities
Solution Approach 1:
The radar system continuously transmits waveform signals and maintains ready-to-process receive channels, enabling immediate detection and tracking of high-speed targets as they enter the detection area. The continuous operation of transmit and receive units ensures no detection delay when targets appear.

AI summary
A detection and tracking radar includes a hazardous zone set within a preset radius based on a main body having a radar, a plurality of detection and tracking sectors configured to detect a high speed mobile approaching the main body within detection areas, the detection areas being defined by diving the hazardous zone based on an azimuth angle, and a controller configured to recognize the high speed mobile as a target based upon signals received from the detection and tracking sectors and track the target. Accordingly, rapid detection and tracking of the high speed mobile can be allowed. Also, since the detection and tracking sectors can be independently run, expansion of a radar system can be free by virtue of addition of the detection and tracking sectors.
