Engineering Contradiction Analysis
1Reliability
If specific data transmission protocols are used in radar systems, then reliable data delivery is ensured, but flexibility for integration with alternative hardware or software components is reduced
Solution Approach 1:
The patent introduces a data packet network with Ethernet-based connectivity and UDP transport as an intermediary layer between the radar engine and external components. This mediator enables flexible integration with various hardware and software components while maintaining reliable data delivery through standardized communication protocols and synchronization mechanisms.
Solution Approach 2:
The radar engine system is designed with universal Ethernet-based communication capabilities that allow it to interface with multiple types of hardware and software components. The system uses standardized data packet formats and synchronization commands that can work with diverse antennas, display devices, and processing units, making the radar system adaptable to different configurations.
2Measurement precision
If synchronized waveform data generation is implemented, then real-time audio processing accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the radar engine receives synchronized waveform data from multiple antennas, processes the data, and generates synchronization commands that are sent back to the antennas. This closed-loop feedback system maintains precise synchronization without requiring complex hardware modifications, as the synchronization is achieved through coordinated data packet exchange and timing protocols.
