Engineering Contradiction Analysis
1Productivity
If electronic attack signals are transmitted to multiple objects simultaneously, then the coverage and effectiveness of electronic attack is improved, but interference between signals to different objects occurs
Solution Approach 1:
The patent segments the electronic attack signal transmission by generating separate beamforming matrices for each object. Each beamforming matrix is specifically designed to direct signals to a particular object while isolating it from other objects, thereby preventing interference between simultaneous transmissions to multiple targets.
Solution Approach 2:
The patent applies local quality by determining specific signal intensities for each object based on individual channel information and beamforming matrices. Each object receives a customized signal intensity tailored to its characteristics, ensuring effective attack while minimizing interference to other objects through spatially selective signal distribution.
2Productivity
If signal intensity is increased to maximize impact on target object, then attack effectiveness on target is improved, but interference to other objects increases
Solution Approach 1:
The patent performs preliminary action by obtaining channel information and generating beamforming matrices before transmitting electronic attack signals. This pre-processing enables the system to calculate optimal signal intensities for each object in advance, ensuring that when signals are transmitted, the target receives maximum impact while other objects experience minimal interference.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting signal intensities based on channel information and beamforming matrices. The system changes the intensity parameter for each object individually, allowing the target to receive high-intensity signals for maximum impact while other objects receive lower intensities to minimize interference.
3Measurement precision
If beamforming matrix is generated to prevent interference, then signal transmission precision is improved, but computational complexity increases
Solution Approach 1:
The patent applies partial action by focusing computational resources on generating beamforming matrices only for the objects that are actual targets of electronic attack. Rather than computing matrices for all possible objects in the environment, the system selectively processes only those objects requiring signal transmission, thereby reducing unnecessary computational complexity while maintaining high transmission precision for targeted objects.
