Receiving monitoring device and receiving monitoring method

摘要

PROBLEM TO BE SOLVED: To solve the problem that other FH communication waves/burst signals/pulse noises which occur simultaneously with hopping timing of FH communication wave signals are erroneously recognized, and that FH communication waves changing hop rate or primary modulation method for each hopping timing cannot be coped with.;SOLUTION: An FH separation circuit 28 focuses attention on the feature that FH communication waves are continuous in terms of time on a frequency-time axis, and that the FH communication waves of a particular frequency channel is always successive between occurrence time and disappearance time. It generates FT matrix on the basis of the information stored in a frequency-time memory 27. The reception signal of the frequency channel having such connection in time between disappearance time and occurrence time as an occurrence time or disappearance time of the reception signal of another frequency channel appears, after the time unit set following disappearance time or occurrence time of the reception signal of particular frequency channel, is detected as the FH communication waves.;COPYRIGHT: (C)2006,JPO&NCIPI
