The invention relates to a ship encountering sector space risk degree space analysis method, which comprises the following steps of: establishing a ship encountering sector space model by taking a ship as a center and taking a detection distance R set by a ship-borne radar as a radius; according to the time gradient range, a sea area space, threatening the main ship, of the target ship is established, judgment is carried out according to the approaching coefficient when the two ship fields are tangent, namely the scaling multiple when the distance is closest, and the scaling multiple lt when the distance is closest; 1, continuing the following steps; determining an encounter fan-shaped space set GP after the target ship G is segmented and an encounter fan-shaped space set QP after the main ship Q is segmented; preliminarily judging the relative positions of the two ships according to the DCPA of the ship and the target ship; the minimum vector distance of the two ships is determined according to the relative heading of the two ships, and the space approaching degree of the combined sector GP is calculated. The method is an analysis method which can simplify a ship encounter space vector structure and accurately excavate and extract encounter space situations and space features of ships in different directions.

    本发明一种基于船舶会遇扇形空间危险度空间分析方法,包括以下步骤:以本船为中心、船载雷达设定的探测距离R为半径,建立船舶会遇扇形空间模型;按照时间梯度范围建立目标船对主船产生威胁的海域空间,根据两个船舶领域相切时的迫近系数,即距离最近时的缩放倍数进行判断,当距离最近时的缩放倍数<1时,继续下述步骤;确定目标船G分割后的会遇扇形空间集合GP,以及主船Q分割后的会遇扇形空间集合QP;根据本船与目标船的DCPA初步判断两船相对位置;根据两船的相对航向确定两船的最小矢距,实现对计算组合扇形GP的空间迫近程度。该方法是一种可以简化船舶会遇空间矢量结构、精确挖掘与提取不同方位船舶会遇空间态势、空间特征的分析方法。
