Dynamic Resource Allocation for Multi-Role Phased-Array Antennas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-role phased-array systems face challenges in dynamically allocating resources for simultaneous execution of RADAR, communication, and electronic-war functions, as existing systems have a static architecture that does not allow for sharing of resources, leading to suboptimal hardware/software performance.
Innovation Solution
A dynamic resource allocation method that operates in the time, space, and frequency domains to allocate resources for antenna functions, allowing for time-sharing, antenna-sharing, and frequency-sharing to optimize resource usage and minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If static resource allocation is used in multi-function systems, then system design is simplified, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation that allows the system to adaptively adjust resource distribution among multiple functions based on real-time requirements. The resource allocator dynamically determines time slots, frequency bands, and antenna elements to be assigned to each function, enabling the system to optimize resource utilization while maintaining design flexibility through software-controlled allocation rather than hardwired static connections.
2Reliability
If resources are exclusively dedicated to single functions, then function execution reliability is improved, but system versatility deteriorates
Solution Approach 1:
The patent creates a universal resource pool that can be dynamically allocated to support multiple different functions including RADAR, communication, and electronic warfare operations. The same physical resources (antenna elements, frequency bands, time slots, processing units) can serve different functions at different times, enabling the system to maintain high reliability for each function while achieving broad versatility across multiple mission types.
Solution Approach 2:
The patent segments resources into discrete allocatable units including time slots, frequency bands, and antenna element groups. This segmentation allows the system to allocate specific segments to specific functions when needed, ensuring reliable execution of individual functions while maintaining the ability to re-segment and re-allocate resources for different function combinations, thus achieving both reliability and versatility.
3Productivity
If time-sharing resource allocation is implemented, then resource utilization is improved, but execution time for individual functions increases
Solution Approach 1:
The patent implements periodic time-sharing allocation where resources are systematically distributed among functions in repeating cycles. The resource allocator creates structured time slots within frame intervals, allowing each function to access dedicated resource portions during its allocated periods. This periodic structure ensures efficient resource utilization across multiple functions while providing predictable execution time bounds for each function within its allocated time slots.

AI summary
A multi-role or multi-function system operable to perform a multi-role or a multi-function and configured to dynamically allocate requisite resources for performing antenna functions during a frame interval of the multi-role or the multi-function by determining whether the antenna functions are completely performable in the frame interval, based on a time-sharing resource allocation procedure; and if not, allocating the requisite resources for performing the antenna functions during the frame interval, based on a time-sharing resource allocation procedure and an antenna-sharing resource allocation procedure.
