Methods for radio frequency spectral analysis

A method for radio frequency spectral analysis comprising:

• providing at least a first UAV and a second UAV, the first UAV and second UAV each including at least a signal detection module and a plurality of filters,
• flying the first UAV in a first flight pattern relative to a signal source,
• utilizing the signal detection module on the first UAV to detect radio signal(s) emanating from the signal source,
• flying a second UAV in a second flight pattern relative to the first flight pattern of the first UAV,
• utilizing the signal detection module on the second UAV to detect radio signal(s) emanating from the signal source, and
• selecting at least one of the plurality of filters in order to selectively filter the detected radio signal(s), the selected filter at least partially corresponding to a downlink band of the detected radio signal(s).
