Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current aircrew decision aids are used, then aircrew can access basic jamming information, but the aircrew workload increases and situational awareness is reduced due to manual processing requirements
Solution Approach 1:
The system automatically calculates Jam Acceptability Regions and generates display outputs without requiring manual aircrew computation. The software self-processes threat emitter data, EA capabilities, and geometric relationships to produce ready-to-display information, eliminating the need for aircrew to manually incorporate PE position and determine optimum EW countermeasures.
Solution Approach 2:
The patent replaces manual mechanical processing of jamming geometry with automated computer-based calculation. The system uses computational algorithms to determine JAR contours and JAS indicators, substituting the aircrew's manual analytical work with electronic processing that provides real-time, accurate results.
2Adaptability or versatility
If manual incorporation of PE position and determination of optimum EW countermeasure is performed, then aircrew can control jamming strategy, but aircrew workload increases significantly
Solution Approach 1:
The system provides dynamic, real-time calculation of JAR contours and JAS indicators that automatically adapt to changing mission parameters. The software dynamically updates displays based on current PE position, threat emitter characteristics, and EA capabilities, providing flexible jamming strategy options without requiring manual recalculations for each scenario.
Solution Approach 2:
The patent segments the complex jamming decision process into distinct visual components: JAR contours showing acceptable regions, JAS indicators showing jamming effectiveness, and multiple display format options. This segmentation allows aircrew to quickly comprehend and select appropriate jamming strategies without processing entire complex calculations manually.
3Productivity
If current display formats are used, then aircrew can view basic position information, but the displays lack flexibility and cannot provide real-time jamming effectiveness assessment
Solution Approach 1:
The system provides multiple display format options that can be selected based on specific mission requirements and threat scenarios. The software universally processes the same input data (EA position, PE position, threat emitter characteristics) to generate different visual representations, allowing aircrew to adapt the display to various assessment needs without requiring separate systems for each format.
Solution Approach 2:
The system performs preliminary calculation and visualization of JAR contours and JAS indicators before the aircrew needs to make jamming decisions. The software proactively generates and updates these assessments in real-time, allowing aircrew to immediately view jamming effectiveness without waiting for manual analysis or post-processing.

AI summary
The invention generally relates to the field of computer software particularly to an improved method of providing aircrew decision aids for use in determining the optimum placement of an Electronic Attack (EA) aircraft. The core of the invention is a software program that will dynamically provide the EA flight crew situational awareness regarding a threat emitter's coverage relative to the position of the EA aircraft and to the position of any number of protected entities (PE). The software program generates information to provide visual cues representing a Jam Acceptability Region (JAR) contour, a Jam Assessment Strobe (JAS) and text for display on a number of flexibly configurable display formats posted on display units. The JAR and JAS graphics and text will aid the EA aircrew in rapidly assessing the effectiveness of a given jamming approach.
