航路规划中数字地图单元格代价计算模型研究

为了解决航路规划中使用的原始数字地图信息量不够全面的问题,结合反舰导弹航路规划的实际作战背景,建立了数字地图单元格代价计算的数学模型.该模型包含了地形高程代价、威胁危险代价、战略回避代价和搜索区目标存在代价等基本模型.通过该模型可以将原始数字地图转化为包含各种相关航路规划主客观信息的综合数字地图.

MC calculation model of grid units on digital map used in route planning

During the route planning,a common problem is the lack of full information in the original digital map.To solve this issue, a mathematic model is built up which is used to calculate the Map Cost(MC) of each grid unit on the digital map during route planning.The model takes the anti-ship missiles route planning as the background.It is designed by integrating many basic models together,such as the terrain elevation cost model,the threatening risk cost model,the stratagem obviation cost model,the target existing in searching area cost model and so on.With the new model,the original digital map can be transformed into a compositive digital map that containing all kinds of related information for route planning.
