Engineering Contradiction Analysis
1Reliability
If all cells in the range-Doppler matrix are analyzed to determine the detection threshold, then the detection reliability is improved, but the computational expenditure and processing time increase significantly
Solution Approach 1:
The patent divides the range-Doppler matrix into multiple cells and selects only a partial quantity of cells for threshold determination, rather than analyzing all cells. This segmentation approach maintains detection reliability by using representative cells while significantly reducing computational load and processing time.
Solution Approach 2:
The patent applies partial action by determining the detection threshold based on only a subset of cells from the range-Doppler matrix. This partial analysis is sufficient to establish a reliable threshold without requiring complete analysis of all cells, thus improving processing efficiency while maintaining detection accuracy.
2Measurement precision
If a detection threshold is determined using all cells of the range-Doppler matrix, then the accuracy of scattering center detection is improved, but the computational resources and time required increase
Solution Approach 1:
The patent segments the matrix into individual cells and selectively analyzes only a partial quantity of them for threshold determination. This segmented approach provides sufficient statistical representation to ensure detection accuracy while reducing processing time compared to analyzing all cells.
Solution Approach 2:
The patent employs partial action by using only a subset of cells to determine the detection threshold. This partial analysis achieves the necessary measurement precision for accurate scattering center detection without the time cost of complete matrix analysis.
3Reliability
If the complete range-Doppler matrix is processed to identify scattering centers, then the detection reliability is improved, but the hardware requirements and computational complexity increase
Solution Approach 1:
The patent segments the detection process into two stages: first determining the threshold using a partial quantity of cells, then applying this threshold to identify scattering centers. This segmentation reduces computational complexity while maintaining detection reliability through the use of representative cell samples.
Solution Approach 2:
The patent applies partial action by using only a subset of cells for threshold determination, thereby reducing the computational complexity required for system implementation. This partial approach maintains sufficient statistical basis for reliable detection without requiring complete matrix processing.
