Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radar systems are vulnerable to countermeasures due to their simple phase fronts, making it easy for aircraft to detect and counter radar emissions, and current methods for locating radar sources are not robust against interference.
Innovation Solution
A radiation source utilizing a superluminal polarization current with an oscillating and accelerated distribution pattern is employed, generating complex phase fronts that are difficult for aircraft to detect, and can be electronically steered without moving the antenna, allowing for robust radar systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional radar systems with simple phase fronts are used, then the system is easy to operate and locate, but the system becomes vulnerable to countermeasures
Solution Approach 1:
The patent applies dynamics by using a phased array antenna system where the phase and amplitude of signals from individual antenna elements are dynamically adjusted in real-time. This creates electronically controllable, complex phase fronts that can be rapidly reconfigured to counter different threats, transforming a static simple phase front into a dynamic complex one that resists countermeasures
Solution Approach 2:
The patent changes the parameters of the radiation field by manipulating the phase, amplitude, and timing of signals from multiple antenna elements. By varying these parameters across the array, the system generates complex phase front patterns with multiple lobes and nulls that are difficult for aircraft to detect and counter, directly addressing the vulnerability of simple phase fronts
2Reliability
If the phase front is made complex to resist countermeasures, then reliability against countermeasures improves, but the device complexity increases
Solution Approach 1:
The patent segments the antenna system into multiple independent radiating elements, each capable of being controlled individually. This segmentation allows the complex phase front to be synthesized by coordinating simpler individual elements, making the overall system manageable despite the complexity of the resulting radiation pattern
Solution Approach 2:
The patent replaces mechanical phase front manipulation (such as physically moving or rotating antenna structures) with electronic control of signal phases and amplitudes. This substitution achieves complex phase front patterns through electronic means rather than mechanical complexity, reducing the physical device complexity while maintaining the desired radiation characteristics
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The complexity of the phase fronts from the superluminal source makes it challenging for aircraft to locate the radiation source, reducing vulnerability to countermeasures and enabling effective radar detection of aircraft and other vehicles.
Implementation Method 1
a radiation source involving phase fronts emanating from an accelerated, oscillating, superluminal (that is, faster than light in vacuo) polarization current
Data Source
AI summary
An apparatus and method for a radiation source involving phase fronts emanating from an accelerated, oscillating polarization current whose distribution pattern moves superluminally (that is, faster than light in vacuo). Theoretical predictions and experimental measurements using an existing prototype superluminal source show that the phase fronts from such a source can be made to be very complex. Consequently, it will be very difficult for an aircraft imaged by such a radiation to detect where this radiation has come from. Moreover, the complexity of the phase fronts makes it almost impossible for electronics on an aircraft to synthesize a rogue reflection. A simple directional antenna and timing system should, on the other hand, be sufficient for the radar operators to locate the aircraft, given knowledge of their own source's speed and modulation pattern.
