Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sensors for intercepting radioelectric emissions face challenges in separating and analyzing radar (RAD) and communication (COM) signals due to their overlapping spectral and temporal domains, leading to increased complexity, mass, volume, and electrical consumption, as well as integration issues on a single platform.
Innovation Solution
An integrated RAD/COM sensor that simultaneously processes both RAD and COM transmissions, with a modular architecture that pools resources from reception antennas to primary processing means, allowing for independent analysis and secondary processing of either COM or RAD signals, enabling monitoring in dense electromagnetic environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate RAD sensors and COM sensors are used to intercept radar and communication signals, then the analysis quality of each signal type is improved, but the device complexity, mass, volume, and electrical consumption increase
Solution Approach 1:
The patent combines separate RAD sensor and COM sensor systems into a single integrated sensor that can simultaneously intercept and process both radar and communication signals. This merging eliminates the need for separate antenna networks, RF receivers, and processing units for each signal type, thereby reducing device complexity, mass, volume, and electrical consumption while maintaining the capability to analyze both signal types
Solution Approach 2:
The integrated sensor is designed with universal functionality to handle multiple signal types (radar and communication) through a single system. The sensor includes a unified antenna network and RF receiver that can capture both RAD and COM emissions, along with a shared processing unit that can analyze different signal characteristics, making the system multi-functional rather than requiring dedicated separate systems
2Adaptability or versatility
If separate RAD sensors and COM sensors are deployed on the same platform, then comprehensive signal interception is achieved, but the integration complexity and material resources required increase
Solution Approach 1:
The patent merges the antenna networks, RF receivers, and processing units of separate RAD and COM sensors into a single integrated system. This consolidation maintains comprehensive signal interception capability while eliminating integration issues related to coordinating multiple separate sensor systems on the same platform
3Adaptability or versatility
If multiple antenna arrays are used to cover the spectral domain for RAD and COM signals, then the spectral coverage is improved, but the volume and mass of the sensor system increase
Solution Approach 1:
The integrated sensor employs a universal antenna network and RF receiver system that can operate across multiple frequency bands (HF, VHF, UHF, SHF) to cover the spectral domain for both radar and communication signals. This eliminates the need for separate antenna arrays for each signal type, thereby maintaining comprehensive spectral coverage while reducing the overall volume and mass of the sensor system
4Measurement precision
If separate processing units are used for RAD and COM signals, then the specialized processing capability is improved, but the electrical consumption and mass increase
Solution Approach 1:
The patent combines the processing units for RAD and COM signal analysis into a single integrated processing system. This unified processor can handle different signal types by applying appropriate processing algorithms, eliminating the need for separate dedicated processing units and thereby reducing electrical consumption and mass while maintaining specialized processing capabilities for both radar and communication signals
