The problem of operationally analyzing spread spectrum frequency-hopping transmissions has been known since the invention of frequency-hopping radios. A frequency-hopping radio transmits a communication using small signal segments of data making up the transmission in accordance to a set of predetermined parameters. In this type of transmission each small segment of data is transmitted at a different frequency, one after another, until the transmission is completed. In some cases, it may be desirable to analyze these radio transmissions and to be able to determine radio spectrum usage and provide a mean to report on interference in frequency bands where multiple types of transmissions are possible. A novel method of isolating multiple transmission signals that are transmitted using frequency-hopping and apparatus is thus proposed which receives at least a transmission and performs operations within frequency bands of the received transmission in order to monitor and characterize signal energy therein.
