Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current countermeasures are inadequate for detecting and neutralizing high-speed aerial and underwater threats, such as missiles and torpedoes, due to limitations in long-range detection and the inability of radio frequencies to propagate underwater, and existing radar systems fail to provide effective defense against these threats.
Innovation Solution
A fractal-antenna based system that transmits and receives EM radiation from high frequency (HF) to ultralow frequency (ULF), using phase shifters and pulse generators to craft electromagnetic waves for detection and neutralization, capable of overcoming Faraday shielding and detecting threats at distances up to 50 kilometers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional radar systems are used for detection, then detection range is limited, but system complexity and cost are reduced
Solution Approach 1:
The system segments the electromagnetic spectrum into multiple frequency bands (HF, VLF, LF, MF) and uses fractal antennas that can operate across these bands simultaneously. This segmentation allows the system to achieve long-range detection capabilities by utilizing different frequency bands for different detection scenarios, rather than relying on a single conventional radar frequency
Solution Approach 2:
The fractal antenna system is designed with multi-functionality to perform detection, communication, and neutralization operations across multiple frequency bands simultaneously. This universal design replaces multiple specialized systems with a single integrated platform that can adapt to various threat scenarios
2Measurement precision
If radio frequencies are used for detection, then long-range detection is possible, but detection underwater is not achieved
Solution Approach 1:
The system changes the frequency parameter of electromagnetic radiation to achieve different propagation characteristics. By operating in the VLF and LF bands (30-3000 kHz), the system achieves both long-range atmospheric propagation and underwater penetration capabilities, as these lower frequencies can propagate through water unlike higher frequency radio waves
3Reliability
If active defensive measures are implemented, then threat neutralization is achieved, but energy consumption increases
Solution Approach 1:
The system uses periodic pulsed transmission instead of continuous wave emission for active defensive measures. The pulse generator delivers high-power electromagnetic pulses at specific intervals to neutralize threats, rather than maintaining continuous high-power transmission. This periodic action achieves threat neutralization while reducing overall energy consumption compared to continuous operation
Solution Approach 2:
The system employs RF-induced transparency (RFIT) which utilizes phase transitions in the electromagnetic interaction with target materials. By crafting specific pulse waveforms that induce resonant responses and phase changes in target electronics, the system achieves effective neutralization with lower energy requirements than conventional high-power microwave approaches

AI summary
A fractal-antenna based system with radar-like detection and communication comprises a fractal antenna array that transmits and receives EM radiation ranging from high frequency (HF) to ultralow frequency (ULF), a phase shifter coupled to the fractal antenna array, a pulse generator coupled to the phase shifter, and a host computer coupled to the phase shifter and the pulse generator. The host computer is configured to: i) control the pulse generator to craft a transmitted wave of selected shape in the time domain, with the ability to enable active defensive measures or detection-only modes, ii) control the phase shifter and antenna to cause radiation to sweep across a coverage radius of at least 5 kilometers, iii) analyze signals received by the fractal antenna array to detect the location and speed of reflective objects in the coverage area, and activate countermeasures based on the location and speed of a detected reflective object.
