摘要： 研究无人机对地目标螺旋式搜索过程中的轨距优化问题。为寻求最优的无人机搜索轨距，根据实际情况建立3种模型。在分析每种模型的优缺点及适应情况的基础上，综合3种模型，建立一个适应各种作战情况的单一参数表达模型，应用近正交试验确定参数表达模型中的参数值。该模型可以解决不同作战环境下无人机对地目标螺旋式搜索过程中的轨距优化问题，可为制定无人机对地目标螺旋式搜索策略提供理论依据。

Abstract: The recommended tracking spacing for an archimedes spiral ground target search of Unmanned Aerial Vehicle(UAV) is studied. To find a recommended track spacing, three models are build according to fact. It analyzes the strengths and weaknesses of each model, describes which condition each model adapted. This analysis combines three analytical functions into a single parameterized expression. To find the best-fit parameters maximizing probability of detection, a simulation experiment with a nearly orthogonal latin hypercube design is used. The model can present a method for solving the optimal setting track spacing for a spiral ground target search of UAV. The research provides a theoretical reference for setting up spiral search strategy.

Key words: Unmanned Aerial Vehicle(UAV), nearly orthogonal latin hypercube experiment, track spacing
