| description | The invention discloses an unmanned ship target identification and tracking method and system based on a navigation radar, and belongs to the field of marine navigation, and the method comprises the following steps: judging whether the predicted relative distance, relative speed and relative acceleration in the next period are consistent with the relative distance, relative speed and relative acceleration collected in the next period or not; if the target information does not have the consistency, replacing the target information, and if the target information has the consistency, predicting and tracking the target; judging whether the measurement distance of the next period is abnormal, if so, replacing the target information, and if not, predicting and tracking the target; and outputting a target prediction tracking or replacement target information signal. According to the method, track information of adjacent front and back periods is acquired and predicted, so that a certain degree of comparison is carri |
