摘　　要：基于双径模型研究了在标准测向场环境下测向精度试验误差的计算模型。通过仿真计算,分析了来波方向、收发天线高度和试验距离等试验参数对测向误差的影响。探讨了测向精度试验中减小测向误差的方法。该方法对于测向试验中合理确定试验参数,客观评价装备,有一定的参考意义。In this paper, a computation model for direction-finding accuracy experiment error in the environment of standard directionfinding site is established based on double-path model. The computer simulation is carried out to analyze the influence of various test parameters （such as arrival wave direction, height of receiving and transmitting antenna and test distance） on direction-finding error. We discuss the method of decreasing direction-finding error in the direction-finding accuracy experiment, which has some reference value for reasonable determination of test parameters and objective estimation of equipment in the direction-finding experiment.
