Abstract
Direct-sequence spread spectrum signals are undetectable by conventional intercept receivers. However, the properties of the m-sequences used to generate such signals give rise to characteristic patterns of triple correlation peaks. These patterns remain discernable for short signal intercepts in the presence of data modulation, other m-sequences and noise, allowing the detection of individual m-sequences
