Effect of Shape of a Ground Scanning Object on Scanning
The ground scanning object studied here is to scan and find a target moving on the ground. An IR sensor installed at the scanning object detects a moving target on the ground. A specially designed platform makes the object fly along a parabolic path with precession. The precession makes the IR sensor plotting a footprint on the ground. In this study, the nutation angle of the object and the footprint are determined for various shapes of the main body. How the scanning capability can be affected by the shape of the main body is investigated. When D/H ratio is 1.1, the nutation angle becomes larger than 90°. In this case the sensor orientation is parallel to the horizontal line, and proper dectection cannot be made.
