The response of frequency-hopping systems to various types of jamming is examined. Fast and slow hopping are defined in terms of the information bit rate. The impact of coding on the jamming susceptibilities of fast and slow hopping systems is analyzed. The required conditions for effective repeater jamming and effective partial-band jamming are explored. Frequency hopping is compared with pseudonoise spread spectrum. The use of different types of data modulation with frequency hopping is discussed.
