Abstract

Amplitude comparison is the simplest method of Radio Direction Finding (RDF) which utilise several directional antennas and compare the signal strength from each antenna to calculate the Angle of Arrival (AoA). There is some jargons mention that more antennas used in amplitude comparison RDF will improve the RDF accuracy. However, a further analysis and real test is still required to support this argument. Therefore, this paper will verify this specific problem by develop 6 antenna RDF system and 4 antenna RDF system then analyse the real test data. A type of printed circuit board log-periodic dipole array (PCB LPDA) antenna is utilised in this paper for the experiment setup. The real test setup and the data collection is explained in this paper to discuss and verify this argument. After the discussion, it is verified that amplitude comparison with 4 antennas has better accuracy than the similar system with 6 antennas.

6和4对数周期偶极子阵列天线无线电测向仪精度比较

振幅比较是无线电测向(RDF)中最简单的方法，它利用多个定向天线，比较每个天线的信号强度来计算到达角(AoA)。有一些专业术语提到，在幅度比较RDF中使用更多的天线可以提高RDF的精度。然而，这一论点还需要进一步的分析和实际测试来支持。因此，本文将通过开发6天线RDF系统和4天线RDF系统来验证这一具体问题，并对实际测试数据进行分析。本文采用一种印刷电路板对数周期偶极子阵列(PCB LPDA)天线进行实验设置。本文通过实际的试验设置和数据采集，对这一论点进行了讨论和验证。经过讨论，验证了采用4根天线的幅度比较比采用6根天线的同类系统具有更好的精度。
