摘要
随着炮位侦察校射雷达作用距离的增加,远程炮位侦察校射雷达如果继续沿用近程炮位侦察校射雷达的外推算法将导致其外推精度变差甚至不可接受,文中在比较远程炮位侦察校射和近程炮位侦察校射差异的基础上,首先进行了远程炮位侦察校射雷达弹道方程的选择,然后研究了基于扩展卡尔波滤波(EKF)算法的远程炮位侦校的实现技术,即推导了新状态方程下的状态转移矩阵等参数,最后利用雷达仿真数据和实测数据进行了验证,发现精度比现有近程算法有很大的提升,表明了算法的正确性、必要性和有效性。文中提出的算法可以在工程实际中得到应用,具有很强的实用性。
With increasing of the operation distance, the precision of long range fire finding radar will get worse if new arithmetic is not used. With the difference between long range fire finding and near range fire finding been discussed, the choice of trajectory e- quation in long range fire finding was studied at first, then the realization technique of EKF arithmetic on the long range fire finding was put forward. Finally the validity of the EKF arithmetic was proved by emulator data and the measurement data of the long range fire finding radar. The arithmetic put forward by this paper can be used in engineer project.
