Real-Time Electronic Warfare Simulation Sub-Frame Sampling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems struggle to simulate precise encounters between high-speed objects, such as aircraft and missiles, within the narrow intervals between frames, leading to errors in determining whether they cross within the operable range of a proximity fuse.
Innovation Solution
A system and method that divide the interval between frames into sub-intervals and sample locations of the aircraft and missile to determine if they encounter each other within the proximity fuse's range, using a proximity fuse control unit to process the missile's explosion when the relative distance is within the explosible distance.

Engineering Contradiction Analysis
1Productivity
If frame-based simulation is used for real-time visualization, then processing speed is improved and real-time display is achieved, but measurement precision of object encounters deteriorates when objects move at very high speeds
Solution Approach 1:
The patent divides the simulation process into two distinct segments: frame-based simulation for general real-time visualization and sub-frame sampling for precise encounter detection. The interval between frames is segmented into multiple sub-intervals during which high-speed objects are sampled at finer time steps to detect encounters that would otherwise be missed due to the coarse frame rate.
2Productivity
If the frame interval is widened to reduce processing load, then productivity is improved, but the ability to detect encounters between high-speed objects deteriorates
Solution Approach 1:
The patent implements dynamic sampling where the sampling interval is adjusted based on object speed and proximity. When objects are moving at high speeds and are within a certain distance threshold, the system automatically increases sampling frequency within the frame interval. This dynamic adjustment ensures reliable encounter detection for critical high-speed scenarios while maintaining efficient processing for normal conditions.
