A low probability in intercept (LPI) analysis shows the effect of scenario-dependent parameters and detectability-threshold factors in jamming and nonjamming environments. The most significant improvement in LPI performance may be obtained by operating at extremely high frequency (EHF) and by maximizing the effective spread-spectrum processing gain and the communicator's antenna discrimination to the jamming signal, and by minimizing the number of symbols in the message. To illustrate this effect, the LPI perfomance between an airborne command post and two advanced satellite-communications systems are analyzed in this paper. The two satellite systems analyzed operate at super high frequency (SHF) (8/7 GHz) and EHF (44/20 GHz).
