Abstract:

Laser radar for vibration analysis represents a military application to develop a target identification system in the future. The problem addressed is how to analyze the vibrations of a target illuminated by the laser radar to achieve a positive identification. This thesis develops a computer-based data acquisition and analysis system for improving the laser radar capability. Specifically, a review is made of the CO2 laser radar, coherent detection, and data acquisition software and signal processing. These aspects form the basis for a laser radar system, using LabView software for data acquisition and signal analysis, which is capable of detecting vibrations from a stationary target. The laser radar was able to detect the frequencies of vibration of a test target. All the data can be recorded by the system. The laser radar presented could be used for further development and production of a target identification system.
