Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for locating improvised explosive devices (IEDs) are limited in effectiveness, as they rely on passive detection and do not efficiently utilize unintentional electromagnetic emissions for detection and disruption, which can be challenging in environments with high background noise or densely populated areas.
Innovation Solution
The Advanced Electromagnetic Location of Electronic Devices (AELED) system combines passive detection with active illumination using high-sensitivity receivers and electromagnetic sources, such as magnetrons, to enhance and analyze RF emissions, allowing for improved detection, location, and suppression of IEDs by altering their radiation characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive detection methods are used to locate IEDs, then the system complexity is reduced, but the detection effectiveness and reliability are insufficient especially in high background noise environments
Solution Approach 1:
The patent combines passive detection receivers with active electromagnetic illumination sources into an integrated AELED system. The receiver detects unintentional emissions from electronic devices while the electromagnetic source actively illuminates targets to enhance their radiation characteristics, merging both approaches to improve detection reliability without requiring separate systems
Solution Approach 2:
The electromagnetic source acts as an intermediary that modifies the radiation characteristics of target electronic devices. By introducing controlled electromagnetic fields, the system enhances the unintentional emissions from IED trigger electronics, making them more detectable by the receiver without direct contact or complex interrogation protocols
2Measurement precision
If active electromagnetic illumination is used to enhance detection, then the emission signatures are amplified for better detection, but the device complexity increases
Solution Approach 1:
The electromagnetic source is designed to operate across multiple frequencies and modes, serving both as an illumination source to enhance emissions and potentially as a disruption mechanism. This multi-functionality allows a single device to perform multiple tasks, reducing the need for separate specialized equipment and managing complexity through consolidation
Solution Approach 2:
The system dynamically adjusts electromagnetic field parameters such as frequency, power level, and pulse duration to optimize detection of different electronic devices. By changing these parameters based on detected signatures and environmental conditions, the system achieves high measurement precision while adapting to various scenarios without requiring completely different hardware configurations
3Reliability
If high field strengths are applied to disrupt IEDs, then the neutralization effectiveness is improved, but the risk of collateral damage and harmful effects increases
Solution Approach 1:
The system applies electromagnetic fields at multiple levels: low-level illumination for detection and enhancement, and higher-level disruption for neutralization. By using partial action (low-level fields) for most operations and reserving excessive action (high-level fields) only when necessary for neutralization, the system achieves reliable disruption while minimizing collateral damage through controlled escalation
Solution Approach 2:
The system leverages the same electromagnetic mechanisms that could potentially cause harm by converting them into beneficial detection and neutralization tools. By carefully controlling the electromagnetic fields, the system uses the devices' own vulnerability to EM energy against them, turning potential harmful effects into the basis for safe detection and neutralization
