无线电测向设备测向误差与数据处理方法研究

Research on Calculation Method of Direction Finding Test Data

通过对某型测向设备的测向精度试验获取的试验数据的分析处理发现，现行的标准和规范中采用的测向误差计算方法没有能够正确区分出设备的能力和试验环境的影响。不能完全客观公正地评价测向设备的真实性能。为了获得合理的测向结果，建议严格按照ITU的有关标准选择测向场地。并选择合适的误差计算方法。

Through the test of DF accuracy, it can be found out that the influences of the environment on the real DF capability of the radio direction finding system can not be accurately discriminated and the practical performance estimation of the desired DF system can not be conducted correctly, by using the calculation method of DF accuracy specified in the current standard and technical specification. Based on the detailed analysis of the actual DF data, it is strongly recommend that more attention should be paid on the assessment of the environment influences on the DF errors and a suitable DF site should be selected according to ITU standard in order to obtain a reasonable DF result.
