Establishing a uniform friend or foe situation map is one of the primary contents in cooperative engagement, which needs to convert the distributed data from sensors into a common coordinate system for implementing data alignment. To solve data alignment problem of multi-platform multi-sensor on the sea, a multi-sensor data alignment method based on relative bearing and range was proposed. Using the measured bearings and ranges of the maritime platforms, the target measurement was transformed into the sensor relative bearing coordinates of a platform for implementing the sensor alignment. Two kinds of coordinate transformation approach for realizing the alignment were studied, with the alignment mechanisms and mathematical models discussed. Through several simulation scenarios, the precision of two transformation approaches were analyzed. Simulation results were used to decide the two approaches' applicable environment according to the precision requirements of the fire-control-level situation.%建立敌我统一态势图是协同作战的一项主要内容,它首先需要将分布的传感器数据变换到公共坐标系中,实现数据位置对准.针对海上多平台多传感器的数据位置对准问题,提出了一种基于舷角一距离的多传感器数据对准方法.利用海上平台互相测量的舷角一距离信息,将目标量测转换到平台的传感器舷角坐标系中,完成数据对准.研究了实现该对准方法的两种坐标转换方式,分别给出对准原理和数学模型.通过不同的仿真剧情对两种对准方式的精度进行分析和比较,并根据火控级态势的精度需求确定两者的适用环境.研究结果对于态势图的建立和海上协同作战具有较高的军事应用价值.
