摘要移动观测平台具有较强的机动特性，在目标探测、战场侦察、监控与监视等领域有广泛的应用前景。采用主被动联合定位方式，可以大大提高观测平台的隐蔽性，从而提高战场生存能力。由于微型移动观测平台一般采用电子罗盘进行定向，其定向精度易受环境因素影响，导致定向定位精度难以满足预期要求。因此本文主要研究利用两个观测平台，在分别测得较高精度斜距离及俯仰角、低精度方位角的情况下，实现对目标的定向定位，且定向定位精度满足预期要求。本文针对双自主移动观测平台的定向定位原理进行了具体研究，给出了具体定向定位算法，同时基于误差传递理论，对单自主移动观测平台及双自主移动观测平台的定向定位精度进行了详细分析，并加以仿真验证。结果表明，本文给出的定向定位算法是有效的，其精度分析可以为实际工程项目设计提供参考。64508

Abstract

Mobile observation platforms with a strong maneuvering characteristic  have a wide range of applications in target detection ,battlefield reconnaissance ,surveillance and monitoring and other fields.Using active and passive joint positioning ,can greatly improve the concealment of observation platform,thereby improving battlefield survivability.Because miniature mobile observation platforms commonly used electronic compass for orientation , its directional precision susceptible to environmental factors , resulting directional positioning accuracy is difficult to meet expectations.Therefore,this paper studies the use of two observation platforms,respectively,measured in distance and high precision helical pitch angle,low-accuracy azimuth circumstances,to achieve directional orientation of the target,and directional positioning accuracy to meet expectations. This paper has a specific study on the directional positioning principle of dual autonomous mobile observation platforms.At the same time, based on the theory of error propagation, directional positioning accuracy of a single autonomous mobile observation platform and two autonomous mobile observation platforms is analyzed in detail, and made simulation.The results showed that the directional positioning algorithm of this paper is effective,and its accuracy analysis can provide references for the actual project design.
