Direction Finding Antennas and Accuracy :Part-2

In the previous blog post (Part-1) we considered some of the ways in which we can express the performance of an DF antenna, and we noted that simply stating the ‘accuracy’ of a DF antenna is not quite that simple.  We also noted that there are various algorithms that can be used along with a typical DF antenna, and that the accuracy and sensitivity of DF system is dependent on both the quality of the antenna and the direction-finding algorithm.In this blog post we will discuss the process of ‘characterizing’ a DF antenna array to generate a table of values which can be used in correlative algorithms.We will also look at a few real-life problems that cause inaccuracies in DF systems, specifically when using basic correlative algorithms.
