Disposable EW Projectile with Parachute for Radar Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for countering surface-to-air missile (SAM) systems and enemy air defenses often rely on expensive, complex manned assets that are vulnerable to detection and counterattack, and existing electronic warfare (EW) solutions require close proximity to maintain effectiveness.
Innovation Solution
A system and method involving a projectile launching device that deploys an EW asset with a detachable parachute, allowing it to float towards the enemy and initiate EW effects such as radar jamming, providing suppression or obscuration of enemy counterfire radar systems without the need for manned assets, using guided or unguided projectiles fired from ground or airborne platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If manned SEAD assets are used to deliver EW effects against SAM systems, then the EW effects can be sustained for the duration of the mission, but the assets are vulnerable to detection and counterattack by the SAM systems
Solution Approach 1:
The patent employs disposable unmanned projectiles or missiles that carry EW payloads to deliver jamming effects against SAM systems. These single-use vehicles are launched, deliver their EW payload, and are then discarded, eliminating the vulnerability of manned assets while sustaining EW effects for the mission duration through coordinated launches
Solution Approach 2:
The patent uses unmanned projectiles or missiles as intermediary carriers to deliver EW payloads to the battlefield. These intermediaries perform the dangerous task of approaching and jamming SAM systems without exposing manned assets, thereby reducing vulnerability while maintaining sustained EW capability through continuous deployment
2Reliability
If SEAD assets position themselves close to SAM systems to sustain EW effects, then the EW effectiveness is improved, but the risk of detection and loss increases
Solution Approach 1:
The system employs disposable unmanned projectiles that can safely operate close to SAM systems to deliver effective EW jamming. Since these are single-use, low-cost vehicles, they can be launched in numbers to ensure coverage while accepting the risk of loss without threatening valuable manned assets
Solution Approach 2:
The patent uses multiple unmanned projectile copies to deliver EW effects simultaneously against SAM systems. These replicated vehicles distribute the risk and provide redundant EW coverage, maintaining reliability through numbers while reducing the vulnerability of any single asset
3Reliability
If friendly indirect fire assets are dispersed and frequently re-positioned for self-protection, then survival against counterfire is improved, but command, control, and logistics complexity increases
Solution Approach 1:
The patent replaces the mechanical system of physically dispersing and re-positioning fire assets with an electronic warfare system that delivers obscuration effects. EW payloads projected onto the battlefield create virtual遮蔽 zones that protect fixed or semi-fixed fire assets, eliminating the need for complex re-positioning while maintaining survival capability
Solution Approach 2:
The system uses EW payloads as intermediaries to create obscuration effects between friendly fire assets and enemy counterfire radars. These electronic obscuration fields act as protective barriers, allowing fire assets to remain in position without direct exposure to enemy detection, thereby reducing logistical complexity while maintaining protection
4Adaptability or versatility
If EW payloads are delivered against templated or suspected counterfire sensor locations, then obscuration effects are achieved without precise location data, but the precision of EW effect delivery is reduced
Solution Approach 1:
The patent employs partial precision by targeting templated or suspected counterfire sensor locations rather than requiring exact real-time location data. Multiple EW payloads are delivered to cover probable enemy sensor positions, achieving sufficient obscuration effects through area denial rather than precise point targeting
Solution Approach 2:
The system uses preliminary intelligence and templating to pre-identify likely enemy counterfire sensor locations before engagement. EW payloads are delivered to these pre-surveyed locations in advance of actual enemy use, creating obscuration effects at probable threat positions without requiring real-time precision tracking

AI summary
An apparatus, system, and method for deployment of an electronic warfare (EW) asset are provided. The system includes a projectile launching device capable of launching a projectile round. An EW asset is detachably carried by the projectile round. A deployable parachute is attached to the EW asset, wherein the EW asset is configured to be suspended from the parachute when the EW asset is detached from the projectile round. The related method is used for suppression or obscuration of enemy counterfire radar (CFR) system by initiating an EW effect by the EW asset as the EW asset floats towards a ground surface.
