一种只有角度信息的传感器关联预处理算法

A Preprocessing Algorithm of Multisensor Association With Only Angle Information

目前已经出现了一些角度关联算法 ,但如何从传感器的所有角度观测数据中提取出可用于角度关联的有效观测数据还很少有人提及。提出了一种利用传感器的最大探测距离和相对位置信息通过几何推导得到的角度观测数据预处理算法 ,并给出了关联张角、候选观测集和有效观测集等新概念。经过该预处理算法 ,可以大大减少进行关联的角度观测数目和产生的假目标数 。

Some angle association algorithms have been developed so far but how to extract the available observations used for association from all angle observations has been less discussed. This paper presents a preprocessing algorithm of angle association which is deduced with maximum detection range of each sensor and relative location of sensors, and gives several new concepts such as association flare angle, candidate observation set and available observation set. Using this preprocessing algorithm, the number of association observations and false targets will be decreased sharply, and the probability of successful association and the real-time performance of the system will be improved.
