| Abstract: |
| Analysing the performance of DS/FH hybrid spread spectrum TT&C signals in jammin
g environment is important for the study of this novel TT&C system.In this paper
expressions for detection probability and false alarming probability of DS/FH
TT&C signals under MTJ (Multi-Tone Jamming) are deduced,the de
tection performance is simulated and analysed with different configuration of D
S and FH spr
eading gain, and valuable conclusion is drawn, which offers references for furth
er research on DS/FH signals application in TT&C system. |
