Reconnaissance System Synchronization with Reactive Jammer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of mobile jammers used to protect vehicles from remote-controlled explosive devices (RCIEDs) causes RF interference that overloads and saturates electronic reconnaissance systems, making them unusable, necessitating the jammer to be switched off during reconnaissance operations.
Innovation Solution
Synchronizing the operation of reactive jammers and reconnaissance systems so that the reconnaissance system receives signals only during the jammer's observation phases, allowing for high-quality reconnaissance while maintaining protection against RCIEDs, with dynamic adjustment of observation and interference phases based on operational requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the jammer emits RF interference to protect against RCIEDs, then protection effectiveness is improved, but the reconnaissance system becomes overloaded and saturated
Solution Approach 1:
The jammer's operation is segmented into distinct observation phases and interference phases. During observation phases, the jammer listens for incoming signals without emitting interference. During interference phases, the jammer emits RF interference to block incoming signals. This temporal segmentation allows the reconnaissance system to operate during observation phases while the jammer provides protection during interference phases.
Solution Approach 2:
The jammer operates in a periodic cycle alternating between observation phases and interference phases. This periodic action creates time windows where the reconnaissance system can perform signal analysis without being overwhelmed by continuous jamming interference, while still maintaining protective coverage when needed.
2Measurement precision
If the jammer is switched off to enable reconnaissance operations, then reconnaissance quality is improved, but protection against RCIEDs is lost
Solution Approach 1:
The operational timeline is segmented into observation phases when the jammer is silent and interference phases when the jammer is active. The reconnaissance system is configured to perform high-quality signal analysis during observation phases, while the jammer provides protection during interference phases. This segmentation enables both functions to operate effectively at different times.
Solution Approach 2:
The reconnaissance system performs signal detection and analysis during the observation phases before the interference phase begins. This preliminary action allows the system to gather intelligence and analyze signals in advance, while the jammer remains ready to provide protection when interference is needed.
3Measurement precision
If the observation phase is extended to improve reconnaissance depth, then signal analysis quality is improved, but jamming efficiency is reduced
Solution Approach 1:
The durations of observation phases and interference phases are made dynamically adjustable rather than fixed. The system can adapt the length of each phase based on operational requirements, such as the complexity of signal analysis needed or the urgency of protection requirements. This dynamic adjustment optimizes the balance between reconnaissance quality and jamming efficiency.
Solution Approach 2:
The temporal parameters of the observation and interference phases can be changed to optimize performance. By adjusting the duration and frequency of these phases, the system can prioritize either reconnaissance depth or jamming efficiency based on the operational context, allowing flexible optimization of performance characteristics.

AI summary
The invention relates to a method for operating an electronic reconnaissance system (2) in surroundings that are protected by a jammer (1).
