Fire Simulation Light Beam Coding for Guided Ammunition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire simulation systems are unable to accurately simulate guided ammunition without reflectors and do not allow for trajectory correction after firing, leading to inefficiencies and increased power consumption.
Innovation Solution
A fire simulation method that determines the trajectory of simulated ammunition, emits a light beam along a simulation axis, and codes it with information, activating the beam only when the ammunition passes a target, allowing for precise simulation of both ballistic and guided ammunition without reflectors and enabling trajectory correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light beam is continuously emitted to simulate ammunition trajectory, then the simulation visibility is improved, but the power consumption increases
Solution Approach 1:
The light beam is emitted periodically only during specific time windows when the simulated ammunition passes near a target, rather than continuously. The transmitter is activated based on timing signals that correspond to the calculated trajectory, creating pulsed illumination that maintains simulation visibility while dramatically reducing overall power consumption.
2Measurement precision
If reflectors are installed on targets to detect light beam position, then the trajectory detection accuracy is improved, but the device complexity increases
Solution Approach 1:
The reflectors are removed from the target system entirely. Instead, the target contains only a detector that directly receives the coded light beam. The trajectory information is extracted from the timing and coding of the light beam itself rather than from reflected signals, simplifying the target device while maintaining measurement precision.
Solution Approach 2:
The light beam itself serves as the intermediary carrying trajectory information. By coding the light beam with trajectory data at the transmitter and having the target detector read this coded information, the system eliminates the need for physical reflectors while preserving the ability to accurately detect ammunition trajectory.
3Loss of information
If the light beam is coded with extensive trajectory information, then the simulation information completeness is improved, but the signal processing complexity increases
Solution Approach 1:
The trajectory information is segmented into discrete coded signals embedded in the light beam. Rather than transmitting continuous complex data, the system divides trajectory parameters into separable coded elements that can be sequentially transmitted and processed, reducing overall processing complexity while maintaining information completeness.

AI summary
A fire simulation method and system for simulating ammunition from a weapon. The method includes determining a trajectory of the simulated ammunition, emitting a light beam along a simulation axis, and coding said light beam with information. The method includes determining a point in time when the simulated ammunition passes a target, determining a value related to the distance between the simulation axis and a momentary position of the simulated ammunition along the trajectory at that point in time, and emitting the light beam coded with the determined value during a predetermined time period.
