摘　　要：电力通信车在通信定位时,会存在大量的干扰因素,影响通信定位效果。为有效提升通信车通信过程的定位精度,提出电力通信移动车干扰下定位技术方法。根据移动电力通信车不同时刻的位置关系,计算径向移动速度;获取通信信号,并对其实施傅立叶变换,采用子空间正交投影方法估计通信源信号,对其实施盲分离处理,实现干扰抑制;将盲分离信号作为输入向量,输入构建的定位框架中,通过训练处理确定通信车定位参数向量,构建定位方程,实现通信车干扰状态下的精准定位。实验结果表明,利用上述方法开展电力通信移动车定位时,定位效果好、精度高。There will be a lot of interference factors in the communication positioning of electric communication vehicles,which will affect the communication positioning effect.In order to effectively improve the positioning accuracy of communication vehicles,a positioning technical method under the interference of electric power communication vehicles is proposed.According to the position relationship of the mobile electric communication vehicle at different times,the radial moving speed is calculated.Communication signals are acquired and subjected to Fourier transform.The subspace orthogonal projection method is used to estimate the communication source signal,and blind separation processing is applied to achieve interference suppression.The blind separation signal is used as an input vector and input into the constructed positioning framework.Through training processing,the positioning parameter vector of the communication vehicle is determined,and a positioning equation is constructed to achieve precise positioning under the interference state of the communication vehicle.The experimental results show that the positioning effect is good and the accuracy is high when this method is used to locate the electric power communication vehicle.
