Summary
This study models active imaging systems for military target acquisition, incorporating coherent effects like speckle and scintillation. Experimental validation confirms these effects act as noise, crucial for system design.
Area of Science:
- Defense and security technology
- Optical engineering
- Signal processing
Background:
- Active imaging systems are advancing rapidly in defense and security.
- Theoretical understanding is needed for military applications like target acquisition.
- Coherent effects can degrade performance.
Purpose of the Study:
- To present a theoretical model for active imaging systems.
- To emphasize the impact of coherent effects (speckle, scintillation).
- To validate the model with experimental human perception tests.
Main Methods:
- Developed a theoretical model for active imaging systems.
- Incorporated coherent effects (speckle, scintillation) as noise sources.
- Conducted human perception tests to validate model predictions.
Main Results:
- Model results show good agreement with experimental data.
- Coherent effects were validated as significant noise sources.
- Demonstrated trade studies for mitigating coherent effects in system design.
Conclusions:
- The developed model accurately represents active imaging system performance.
- Understanding and mitigating coherent effects are critical for effective target acquisition.
- The research provides a foundation for designing improved active imaging systems.
