摘　　要：对地球表面三维空间进行远程监视覆盖有利于早期发现入侵目标。构建了地球表面曲率影响下的三维目标空间模型以及传感器三维感知模型,提出了覆盖优化算法。该算法将地球表面三维目标空间离散化处理,利用地(海)面固定位置三维有向传感器网络对目标空间感知监视,采用智能优化算法优化调整三维有向传感器主感知方向的方位角和俯仰角,从而最大化传感器网络对目标空间的监视覆盖率。Remote surveillance coverage for three-dimensional(3D)space on the Earth’s surface is conductive to early detection of intrusion targets.A 3D target space model under the influence of the curvature of the earth’s surface and a 3D sensing model are constructed.And a coverage optimization algorithm is proposed.In this algorithm,the 3D target space on the Earth’s surface is discretized.The 3D directional sensor networks with fixed position are used to monitor the target space.The azimuths and elevations of the main sensing directions of the 3D directional sensors are adjusted through intelligent optimization algorithms to maximize the coverage ratio of the target space.
