| * Updates: | * Updates: | ||
| + | * Inaccuracies in single microphone wind speed algorithm due to assumption that all microphones are set the same way | ||
| + | * To fix this, microphones were re-calibrated individually, each microphone calibrated with 8 wind speeds | ||
| + | * Peak detector coefficients were determined for each microphone | ||
| + | * Raw wind direction tests were conducted from 0 to 360 degrees using the new peak detector equations | ||
| + | * Peak detector outputs of each microphone with the north microphone at 0 to 360 degrees were plotted | ||
| + | * Using this raw data, microphone angle and ratio of the two largest microphone readings at each angle were plotted | ||
| + | * A linear relationship was derived mapping the microphone angle to this raio | ||
| * To Do: | * To Do: | ||
| + | * Conduct tests to verify relationship | ||
| + | * Look at implementing some other filters (i.e. FIR) | ||
