1. A method for identifying ambient signal data in a test signal data set, the method comprising:
identifying, via a number of processors, a cumulative amplitude distribution of data elements in the test signal data set wherein the data elements are in order by amplitude values, wherein the data elements comprise frequency values and corresponding amplitude values; identifying a subset of data elements from the test signal data set, wherein the subset of data elements comprises the data elements with the amplitude values greater than a first threshold value; identifying the data elements in the subset of data elements wherein a difference between the amplitude values of adjacent data elements in the cumulative amplitude distribution of data elements is greater than a second threshold value; and using the test signal data set to perform an interference path loss measurement for an aircraft after removing from the test signal data set the data elements identified by identifying the data elements in the subset of data elements. |
