Abstract: An image processing device comprises a trail extraction section that extracts a region where pixel values continuously become a given value or more, within image data made up of a plurality of pixel values, as a trail, a trail determination section that determines movement state of the trail that has been extracted by the trail extraction section, and a trail detection section that detects type of the trail based on movement state that has been determined by the trail determination section.
Abstract: This disclosure provides an image processing device, which includes an actual trail image memory for storing an actual trail data group indicating absolute changes in position of a target object detected by echo signals obtained corresponding to detection signals transmitted while changing an azimuth direction of the transmission, and a moving target object determination processing module for determining whether the target object detected with the detection signals is a moving target object based on the actual trail data group.
Abstract: A radar system comprises an optical fiber RF storage subsystem for storing a portion of RF signals before the transmission. The radar system further comprises a coherent RF receiver to process reflected RF signals using stored RF signals as a reference. Furthermore, the optical fiber RF storage system is used to store initially received RF signals for comparison with sequentially received RF signals.
