A new method of Frequency-Hopping (FH) signal detection

A new Frequency-Hopping (FH) signal detection method is proposed. Different from previous methods which need to monitor the total band, it can monitor part of the band and decrease the range of the bandwidth. According to this method, a new detection model is set and the computation formulas of the detection probability and false-alarm probability are given. The parameters of a VHF radio are used to prove the validity of the method. Simulation results show that this method can decrease the range of the bandwidth and detect the FH signal with some penalty on the SNR and signal loss.
