Distributed Electronic Warfare Jamming Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic warfare systems are inflexible and vulnerable in complex battle scenarios, particularly when combating multiple threats, as they rely on stationary central control sites and manual coordination of jamming signals.
Innovation Solution
A method for producing jamming signals that allows for dynamic coordination between cooperating vehicles, where stations exchange availability and threat status data to determine if one should assume a central planning function, optimizing jamming signal emissions based on geometric relationships and resource availability, enabling efficient combat of multiple threats without a stationary central control site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stationary central control site is used to coordinate jamming signals, then coordination capability is improved, but system vulnerability and inflexibility increase
Solution Approach 1:
The central control function is segmented from a single stationary site and distributed to multiple mobile stations. Each station can independently perform central planning functions when needed, eliminating the single point of failure and enabling flexible reconfiguration of control authority based on operational requirements.
Solution Approach 2:
The system transitions from a static central control architecture to a dynamic distributed architecture where any station can assume the central planning function. The control capability moves with the stations, allowing the system to adapt to changing battle scenarios and maintain coordination without a fixed control site.
2Device complexity
If manual coordination of jamming signals is used, then system simplicity is improved, but combat efficiency against multiple threats deteriorates
Solution Approach 1:
The system implements automated resource management where stations automatically exchange availability status data and coordinate jamming signals without manual intervention. The resource handling unit at each station autonomously determines optimal signal coordination based on geometric relationships and threat positions, eliminating the need for manual operator coordination while maintaining system simplicity.
3Reliability
If jamming signals are emitted continuously, then jamming effectiveness is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic assessment of jamming requirements by continuously monitoring availability status data and threat positions. Jamming signals are emitted only during periods when threats are detected and coordination is required, rather than continuous emission. This periodic activation maintains jamming effectiveness while significantly reducing energy consumption during non-threat periods.

AI summary
The invention relates to a distributed electronic counter measures solution, wherein jamming signals (JA; JB) may be emitted towards threats (X1, X2) from counter measures stations in multiple vehicles (A, B), which are physically separated from one another in order to improve the chances of survival the vehicles (A, B) as well as any other vehicles that are associated with these vehicles (A, B) in a group of vehicles. The vehicles in the group exchange messages (D) over a wireless data link (L), where the messages (D) sent from a particular station specify an availability status (Dres-status) for each electronic warfare resource in the station and a threat status (Dthr-status) registered by the station. A station in the group having a central planning function coordinates any jamming signals (JA; JB) emitted from the electronic warfare resources of the stations in the group, such that the resources are optimally used with respect to all of any registered threats (X1, X2). This coordination is based on estimated geometric interrelationships between the at least two stations in the group; estimated geometric relationships between the at least two stations in the group and at least one registered threat (X1, X2); and the respective resources of each station in the group.
