Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic warfare systems face performance degradation and security issues due to interference in RF resource access among single-function systems, leading to slow response times and increased target vulnerability.
Innovation Solution
A multi-function resource-managed RF system architecture with a multi-tiered approach and a greedy fill algorithm that prioritizes and allocates RF resources without using blanking lines, allowing multiple tasks to share resources while minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mission computer fulfills the needs for antenna aperture and RF spectrum access of one system, then that system's communication needs are satisfied, but other systems are interfered with or prevented from accessing these communication resources
Solution Approach 1:
The patent combines multiple single-function systems into a multi-function system where a single mission computer manages antenna aperture and RF spectrum resources for multiple functions (electronic attack, electronic support, communications, intelligence). This merging eliminates inter-function interference by consolidating resource access through a unified management architecture that dynamically allocates resources based on task priority and requirements.
Solution Approach 2:
The mission computer is designed as a universal platform that performs multiple functions (electronic attack, electronic support, communications, intelligence) rather than being dedicated to a single function. This multi-functionality allows the system to dynamically allocate antenna aperture and RF spectrum resources across different operational contexts, preventing interference between previously separate single-function systems.
2Device complexity
If blanking lines are used to manage communication resources, then resource allocation is simplified, but response times increase and performance deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where the mission computer continuously monitors task requirements and adjusts antenna aperture and RF spectrum assignment in real-time based on changing operational conditions. This dynamic management replaces static blanking line approaches, allowing the system to respond quickly to new threats or opportunities without being constrained by pre-configured resource partitions.
Solution Approach 2:
The system changes operational parameters (frequency, aperture direction, power level) dynamically based on task priority and environmental conditions. Rather than using fixed blanking lines that prevent parameter changes, the mission computer actively adjusts these parameters to optimize performance across multiple functions, reducing response time while managing complexity through intelligent control algorithms.
3Reliability
If single-function systems are used, then each system has dedicated resources, but inter-function interference occurs and situational awareness deteriorates
Solution Approach 1:
The patent merges multiple single-function systems into an integrated multi-function system where all sensors and processors contribute to a unified situational awareness picture. By combining electronic attack, electronic support, communications, and intelligence functions under a single mission computer, the system eliminates information silos and enables cross-functional situation awareness while maintaining reliable resource allocation through centralized management.

AI summary
Embodiments of a system and method for using radio frequency (RF) resources are generally described herein. In some embodiments, the system includes an antenna subsystem including antenna apertures. The system may also include devices configured to execute a plurality RF tasks. The system may further include memory to store a prioritized list of RF tasks. The system may still further include a manager to receive a request from an RF task to use an antenna aperture. The manager may insert the RF task into a prioritized list of RF tasks within a time duration specified in the request. The manager may spawn a thread to execute the RF task through the antenna aperture, within a time frame depending on the RF task's position in the prioritized list.
