Apparatus for estimating future position of target navigating in water
专利汇可以提供Apparatus for estimating future position of target navigating in water专利检索，专利查询，专利分析的服务。并且PURPOSE: To achieve the optimum tracking by mounting a means estimating the motion of a target from the azimuth data of the target navigating in water and an own position and a means estimating the future position of the target from the result estimated by said means.
CONSTITUTION: The azimuth of a target 21 and an own position 22 are used as data to estimate the motion of the target 21 by a target motion estimating apparatus 1. This estimated value is used to output the future position of the target 21 by a future position estimating apparatus 2. In order to estimate the future position, the speed component in a direction X of the target is set to A
1 , the initial coordinates are set to A
2 , the speed component in a direction Y is set to A
3 and the initial coordinates are set to A
4 and A
1 - A
4 are defined according to a predetermined evaluation functional formula. This evaluation functional formula is partially differentiated and predetermined simultaneous equations are solved to obtain A
1 - A
4 and the future position of the target is calculated.
