摘要
目前我国的雷电探测定位系统的定位精度一般是1 km以内,其原因主要是在雷电探测过程中涉及诸多因素,这些因素最终给雷电探测带来大小不同、性质各异的误差,从而使雷电定位结果中含有较大误差。尽管我国的地闪探测采用的是综合法,但其基础还是到达时间法,本文针对这种状况,对到达时间法雷电探测技术探测误差进行了分析,提出了相关误差的改正计算公式和改正方法,并通过试验,对我国雷电探测站时间同步的精度进行分析和验证。
The location positioning accuracy of the China lightning detection system is usually within 1 km because of involving many influencing factors in lightning ddection process. The factors bring differcnl errors which induce significant errors in the results of the lightning location. Although the comprehensive lightning detection method has been used in China, it is based on TOA. The errorsof TOA were analyzed and the correction formulas as well as method were put forward in the paper. Then the time synchronization accuracy was analyzed and validated by experiment.
