Spectrum Management Processor for Anti-Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy military radio systems operating in VHF and UHF bands, along with GPS systems, are susceptible to jamming, leading to communication and navigation disruptions in contested areas.
Innovation Solution
An applique system with circuitry and a spectrum management processor that provides alternative position, navigation, and timing (PNT) channels by switching to alternate RF channels, utilizing HF and multi-band antennas, and datalinks to manage the spectrum and counter jamming, allowing communication and PNT information to continue even when GPS and VHF/UHF bands are disrupted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If legacy military radio systems operate in VHF and UHF bands with GPS, then communication and navigation functions are provided, but the systems are susceptible to jamming and signal disruptions in contested areas
Solution Approach 1:
The system dynamically switches between different frequency bands (VHF, UHF, HF) and communication modes based on real-time spectrum conditions. The spectrum management processor continuously monitors for jamming and automatically transitions to alternative frequencies or communication methods, making the system adaptable to contested electromagnetic environments rather than static and vulnerable
Solution Approach 2:
The system changes operational parameters including frequency band selection, modulation schemes, and communication protocols in response to detected jamming. By varying these parameters dynamically, the system can evade detection and interference, maintaining reliable communication despite adversarial actions
2Reliability
If the entire radio system is replaced to improve anti-jamming capability, then reliability in contested areas improves, but cost and complexity increase significantly
Solution Approach 1:
The system is divided into modular components: the existing legacy radio remains intact while a separate spectrum management processor and additional antennas are added as independent modules. This segmentation allows the new anti-jamming functionality to be introduced without replacing or disrupting the proven legacy infrastructure
Solution Approach 2:
A spectrum management processor acts as an intermediary layer between the legacy radio and the electromagnetic environment. This intermediary monitors spectrum conditions, makes intelligent decisions about frequency selection, and coordinates communication across multiple bands, providing advanced anti-jamming capability without requiring modification of the core legacy system
3Reliability
If alternative RF channels are implemented for PNT information, then navigation reliability improves under GPS disruption, but system complexity increases
Solution Approach 1:
The spectrum management processor performs multiple functions: it manages VHF/UHF communications, handles HF communications, scans for available frequencies, detects jamming, and provides position navigation and timing information. By consolidating these diverse functions into a single intelligent processor, the system achieves multi-functionality without proportionally increasing complexity

AI summary
Embodiments of the present disclosure relate to a spectrum control system. The system comprises one or more high frequency (HF) antennas, one or more multi-band (MB) antennas, and one or more datalinks. A spectrum management processor is configured to receive signals from the one or more HF and MB antennas and the one or more datalinks, and switch to one or more alternate radio-frequency (RF) channels for communications and/or position, navigation, and timing (PNT) information in response to a failure in a current communication channel and/or a global positioning system (GPS) signal.
