Solution Overview
Problem
Modern military formations face challenges in protecting themselves from electronic identification and targeting due to limitations in existing expendable active decoys, which can only generate signals for a single aircraft, failing to effectively mimic the electronic signature of larger formations.
Innovation Solution
A programmable battlefield decoy system utilizing a System on a Chip (SoC) with FPGA programmable logic, capable of transmitting multiple waveforms to mimic the electronic signature of military formations, including software-defined radio waveforms, and featuring redundancy and re-programmability to adapt to different scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional expendable active decoys are used, then single aircraft signal generation is achieved, but formation-level electronic protection is lost
Solution Approach 1:
The RF generator is designed to perform multiple functions: it can generate signals for single aircraft as well as for entire military formations. The system includes a library of waveform templates representing different military units (artillery, mechanized, ground troops) and can selectively activate appropriate signals based on deployment scenario, making the device universally applicable across different protection needs.
Solution Approach 2:
The signal generation capability is segmented into multiple independent waveform templates, each representing a different military unit type. The system divides the formation protection function into separate signal channels that can be independently configured and activated. This segmentation allows the single device to simulate multiple distinct signal sources simultaneously.
2Adaptability or versatility
If waveform templates for multiple military units are integrated, then formation signature mimicry is improved, but device complexity increases
Solution Approach 1:
Multiple waveform generation functions are merged into a single integrated RF generator device. Rather than using separate decoy devices for each military unit type, the system combines all waveform templates and signal generation capabilities into one unified platform, reducing the number of components needed while maintaining full functionality.
Solution Approach 2:
The system uses programmable parameters and software-controlled waveform selection to achieve variety without hardware complexity. By changing software parameters and activating different waveform templates based on the desired military formation type, the system adapts its signal output without requiring physical reconfiguration or additional hardware components.
3Adaptability or versatility
If programmable multi-waveform capability is implemented, then re-programmability and adaptability are improved, but manufacturing complexity increases
Solution Approach 1:
The system replaces physical hardware reconfiguration with software-based waveform programming. Instead of requiring different hardware components for different military unit simulations, the invention uses programmable waveform templates that can be loaded and activated through software, dramatically simplifying manufacturing while enabling full re-programmability for different deployment scenarios.
