Laser Missile Guidance Stabilization for Moving Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current missile guidance systems, particularly those used in moving vehicles or tanks, face precision issues when targeting moving targets on uneven terrain or in windy conditions, due to rudimentary direction modification capabilities and integration with optical systems.
Innovation Solution
A motorized platform with servo-control along two axes in elevation and azimuth, independent of the sight system, stabilizes the laser guidance line relative to the gyrostabilized line of sight, ensuring continuous parallelism and precise alignment, allowing for enhanced precision and flexibility in targeting moving targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the laser guidance system is integrated into the sight system of the armored vehicle, then the system complexity is reduced and integration is improved, but the precision and stability of laser pointing deteriorates when the vehicle or target is moving
Solution Approach 1:
The system separates the laser guidance system from the sight system, making them mechanically independent. The laser guidance system includes its own separate platform with motors for azimuth and elevation control, while the sight system remains integrated with the turret. This segmentation allows each subsystem to be optimized independently, resolving the contradiction between integration and precision.
2Device complexity
If the laser guidance line is mechanically coupled to the turret or sight system, then the device complexity is reduced, but the stability of the laser guidance line deteriorates when the vehicle moves or when subjected to wind and uneven terrain
Solution Approach 1:
The system introduces an intermediary control mechanism - a separate platform with motorized azimuth and elevation control - that mediates between the turret movements and the laser guidance line. This intermediary platform receives control signals independently and adjusts the laser position accordingly, preventing direct mechanical coupling from transmitting vibrations and movements from the turret to the laser system.
3Device complexity
If manual control is used to modify the guidance line direction by moving the turret or guidance system, then the device complexity is reduced, but the ease of operation and firing opportunities deteriorate when targeting moving targets
Solution Approach 1:
The system implements self-service control where the laser guidance system automatically tracks and follows the line of sight without requiring manual turret movement. The separate motorized platform continuously adjusts the laser position based on target acquisition data, enabling automatic engagement of moving targets and significantly improving ease of operation while maintaining relatively simple control architecture.
