| Summary: | 碩士 === 國防管理學院 === 國防資訊研究所 === 96 === There are two types of remote sensing imagery -- radar and optical. The radar imagery is created by a satellite which radiates electromagnetic wave onto its target. The satellite then receives the reflected energy and downlinks the reflection to a ground station which processes the reflection into imagery. The optical imagery is created by a satellite which collects sun light reflection from its target through an optical lens. The satellite then records the reflection with a sensor and downlinks the sensor data to a ground station for further processing into imagery. Target visibility with optical imagery is easily impaired by weather effects such as haze, fog, cloud and rain, etc., while radar imagery is immune to the above limitations, because the electromagnetic radiations and reflections penetrate through the weather and therefore unaffected by the elements.
The objective of this study is to implement the Second Order Affine Process and then resample the radar imagery with Bilinear Interpolation Method to effectively integrate the two type of imagery together. The results are easier target identification with radar imagery and a coarse display of targets under the weather obscured areas with an optical imagery. Recommendations proposed by this research pave a way for further investigations as well as practical implementations in this area of science.
