Frequency　Hopping　(FH)　systems　are　increasingly　popular　in　contemporary　wireless　communications,　especially　in　military　communications　and　electronic　confrontations.　The　key　performance　of　FH　systems　includes　robustness,　continuation,　and　resilience.　To　measure　these　factors,　additional　interference　is　introduced　into　FH　systems,　and　a　large　number　of　algorithms　and　schemes　have　been　proposed　to　maximize　the　probability　of　interception　while　maintaining　the　Radio　Frequency　Interferences　(RFI)　detection　probability　level.　In　this　paper,　we　propose　a　Rapid　Optimization　approach　(RO)　to　search　for　the　maximum　value　of　interception　probability　without　the　increase　of　RFI　detection　probability.　Three　experimental　factors　are　considered　i.e.,　total　system　power,　distance　between　the　RFI　node　and　the　receiving　node,　and　the　number　of　occupied　sub-channels　with　Nakagami-m　fading　and　Rayleigh　fading　models.　Numerical　results　show　that　the　searching　speed　of　the　proposed　approach　is　significantly　reduced　compared　to　the　existing　algorithm,　and　sub-optimal　point　of　interception　probability　is　almost　as　good　as　the　optimal　one.　©　2017　IEEE.
