3D Moving Target Indication System for Multi-Target Distinguishability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving target indication (MTI) systems struggle to effectively distinguish between multiple moving targets in a geographic scene, often blending them together due to two-dimensional representations, making it difficult to track and identify individual targets.
Innovation Solution
A three-dimensional MTI system that integrates time-sampled location indicators into geography data, assigning each indicator a height corresponding to its sampling time, allowing for a visual representation of moving targets' movement and velocity calculation, enhancing distinguishability and tracking capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two-dimensional MTI representations are used, then system complexity is reduced, but target distinguishability deteriorates
Solution Approach 1:
The patent transitions from two-dimensional MTI representations to three-dimensional visualizations by adding a vertical dimension that represents time. Each moving target is depicted as a three-dimensional object with height corresponding to its temporal position, allowing multiple targets to be distinguished in the vertical dimension even when they occupy the same horizontal space. This dimensional change resolves the contradiction by improving target distinguishability without proportionally increasing system complexity.
2Area of stationary object
If multiple moving targets are represented in the same plane, then display space is optimized, but tracking capability deteriorates
Solution Approach 1:
The patent employs three-dimensional visualization where moving targets are represented at different heights corresponding to their temporal positions. This allows multiple targets to be displayed within the same horizontal footprint while maintaining distinguishability through vertical separation. The time-sampled location indicators are stacked vertically, enabling operators to track multiple targets simultaneously without requiring additional display space, thus resolving the contradiction between display space optimization and tracking capability.
3Ease of operation
If time-sampled location indicators are superimposed at the same height, then visual integration is improved, but target identification deteriorates
Solution Approach 1:
The patent assigns different heights to time-sampled location indicators based on their temporal positions. The most recent sampling time is represented at a higher position than previous samples, creating vertical stratification of target history. This allows the visual integration of multiple time points while maintaining clear target identification through height-based differentiation. The three-dimensional representation enables operators to distinguish between targets at different temporal positions even when they occupy the same horizontal location, resolving the contradiction between visual integration and target identification.

Function Achieved in This Case
The system provides clear, three-dimensional visualizations of moving targets, enabling better distinction and tracking, even when targets are close in proximity, and allows for real-time updates and velocity calculations, improving surveillance and reconnaissance applications.
Implementation Method 1
a typical MTI system can implement a radar system to detect the moving target based on the Doppler effect, such that a sequence of radar pulses can experience a Doppler shift in response to the moving target changing a location with respect to the radar system
