 Choose between various direction-finding algorithms. In almost all cases you will want to use the MUSIC algorithm.

-Forward-Backward Averaging. When you use a linear ULA array, this can be enabled and may improve multipath rejection.
+Correlated signals is another term for multipath signals. Multipath reflections will be correlated with the actual signal, and special algorithms can be used to try and reduce their effect. The algorithm selectable in this drop down menu can help remove unwanted correlated signals. 
+
+These decorrelation algorithms are designed to work with ULA arrays. However, if a UCA array is used, and a decorrelation algorithm is enabled, a special experimental 'virtual ULA' array will be calculated from the UCA array geometry. This trick allows for decorrelation algorithms to work with UCA arrays. However, it is important to note that the virtualization could introduce errors AND it will only work with large radius arrays that have wavelength multipliers close to the maximum of 0.5 for a particular frequency.
+
+You can experiment with each decorrelation method. Currently this is new and experimental and we do not have enough information to know in what scenarios and what algorithms will work best.
