Solution Overview
Problem
Existing directed energy weapons (DEWs) lack precision, often disrupting or destroying unintended electronic devices and revealing the location of the DEW to hostile forces, posing a risk to the weapon and its operator.
Innovation Solution
A high-energy radio frequency (HERF) weapon that emits directed radio frequency energy at specific frequencies and locations associated with targets, such as UAVs, using locational and frequency information from a passive surveillance system, thereby disabling or destroying the target without affecting nearby devices and minimizing detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If broad spectrum RF energy is emitted to disrupt electronic devices, then the ability to disable targets is improved, but collateral damage to nearby devices increases and detection risk increases
Solution Approach 1:
The patent applies local quality by directing RF energy at specific localized frequencies that correspond to the resonant frequencies of the target device's electronic circuits. Instead of emitting broad spectrum energy that affects all devices, the system identifies and targets only the specific frequency signature of the intended target, thereby disabling it while leaving nearby devices operating on different frequencies unaffected.
Solution Approach 2:
The system changes the parameter of RF energy emission from broad spectrum to narrowband targeted frequencies. By analyzing the target's electronic circuitry characteristics and emitting energy at those specific frequencies, the system achieves selective disruption. The patent also adjusts energy parameters dynamically based on target identification to maximize effectiveness while minimizing collateral impact.
2Reliability
If broad spectrum RF energy is emitted to ensure target disruption, then the effectiveness against unknown targets is improved, but the location of the DEW device is revealed to hostile forces
Solution Approach 1:
The patent applies preliminary action by first passively identifying and characterizing the target device's frequency signature before emitting disruptive RF energy. The system performs spectral analysis of the target's electronic emissions or communications to determine its operating frequencies, then prepares targeted energy parameters in advance. This preliminary identification phase allows the system to plan precise frequency-specific attacks without broadcasting its location, as no energy is emitted during the identification phase.
3Object-affected harmful factors
If precise frequency targeting is used to minimize collateral damage, then selectivity against specific targets is improved, but the complexity of frequency identification and targeting increases
Solution Approach 1:
The patent applies self-service by enabling the target device to reveal its own frequency characteristics through its normal electronic operations. The system passively monitors and analyzes the electromagnetic emissions, communications, or power consumption patterns of the target to automatically identify its frequency signature. This eliminates the need for complex active probing or manual identification, as the target essentially identifies itself through its operational emissions, simplifying the targeting process while maintaining high selectivity.
