RF Event Sequencer for Real-Time Priority Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RF communication systems in Electronic Warfare devices face challenges in managing complex scenarios that require real-time prioritization of operations, such as jamming, signals intelligence, and tactical communications, with existing sequencers failing to adequately address these demands.
Innovation Solution
A sequencer system for RF communications that includes a processor and memory to sequence operations, prioritizing high-priority transmit operations like jamming, and controlling power-up/down sequences of transmitters and receivers, with features like guard intervals and various gain control modes for receivers, and jamming modes for transmitters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed sequencer provides fixed periods of time at pre-determined bandwidths for different functions, then the order of operations is fixed and predictable, but the system cannot respond to real-time priorities or complex military-specific events
Solution Approach 1:
The sequencer transitions from a static, fixed schedule to a dynamic event-driven architecture where operation timing and prioritization are determined by real-time events and priority levels. The system can dynamically adjust the order of operations based on incoming signals and predefined priority rules, allowing high-priority operations to interrupt or preempt lower-priority ones while maintaining overall system predictability through structured event handling.
2Speed
If the sequencer switches the transceiver to receive signal model as soon as an incoming signal is detected, then incoming communications signals are received in real time, but any signal transmission that is occurring is temporarily paused
Solution Approach 1:
The system introduces an event-driven intermediary layer that mediates between incoming signal detection and transceiver mode switching. Instead of immediate switching, the event sequencer evaluates the incoming signal against predefined priority rules and event conditions, allowing high-priority transmit operations to continue or be properly managed while still enabling timely response to critical incoming signals through structured event handling rather than direct interruption.
3Speed
If the system implements real-time prioritization of high-priority transmit operations like jamming, then these operations are carried out in real-time upon request, but other functions may be impacted
Solution Approach 1:
The system segments operations into distinct priority levels and event categories, allowing high-priority transmit operations to be handled separately from lower-priority functions. The event sequencer processes events in structured phases and uses priority-based scheduling to ensure that critical operations execute in real-time while maintaining dedicated resource allocation and operational windows for other functions, preventing performance degradation through systematic separation of concerns.
