一种异类传感器的异步数据融合算法

由于雷达具有较好的测距性能,红外传感器具有高精度的测角性能。由于上述技术特点,使得两者具有良好的信息互补性,雷达和红外数据融合引起了广泛的注意。异类传感器数据处理是数据融合中的一个难点。考虑到两种传感器具有不同的测量维数,量测数据异步采样并以不同的速率传输到融合中心站点,提出了一种新的异类传感器异步数据融合算法。通过最小二乘法完成两种异步数据关联同步,然后对于相似性测度进行数据关联,与数据压缩技术完成目标状态信息融合。利用上述方法,进行了仿真实验验证了算法的有效性。

An Algorithm for Asynchronous Data Fusion of Heterogeneous Sensors

Radars have sound performance in orientation measure and infrared sensors have excellent performance in angle measure,which enables the two kinds of sensors complementary each other with information.But heterogeneous sensor data disposal is a difficult problem in data fusion.It is assumed that these sensors are asynchronous and the observation data are transmitted to a central station at a different rate.Think about these factors,the paper describes a new algorithm of data fusion based on the heterogeneous ...
