摘要
PROBLEM TO BE SOLVED: To automatically and accurately detect the speed and navigation direction of a ship according to a ship image being detected from the image of an earth surface being photographed by the synthetic aperture radar of an artificial satellite. SOLUTION: A ship is detected by a ship detection part 4 based on the image amplitude ratio of satellite SAR sea-surface image data 1 where a land part is eliminated in advance for treatment and a threshold, furthermore, the Hough transform of the upper and lower sides of the ship being detected by a track detection part 5 is used for detecting a track, and Doppler shift is calculated by a ship-side detection part 6 according to the amount of deviation between a navigation position and a ship position for detecting the speed of the ship, thus accurately detecting the speed and the navigation direction of the ship according to a satellite SAR image.
