摘 要：
PROBLEM TO BE SOLVED: To provide a jamming device which searches for an FH signal in a very short time after starting communication of a frequency hopping system and performs
jamming. ;SOLUTION: This device is provided with a receiving means that receives a radio signal and outputs a received signal, a 1st extracting means which extracts a radio signal arriving in a known direction from the received signal as a hopping signal, a 2nd extracting means which extracts the hopping signal of a hop destination of the extracted hopping signal from the received signal on the basis of the known timing between the hopping signals and a jamming
means which radiates jamming signals on the basis of the frequency the hopping signal extracted by the 2nd extracting means.;COPYRIGHT: (C)2001,JPO 主权项：
