The analysis presented in this report is concerned with the use of direct-sequence, spread-spectrum signals in nonprocessing satellites. Such signals are designed to provide protection against jamming. Direct-sequence, spread-spectrum signals mitigate the effects of jamming by spreading the energy of the desired signal over a much wider bandwidth than is required when using conventional nonantijam signaling techniques. This spreading is done by using a suitable pseudorandom sequence, which makes it possible to recover the desired information content while rejecting much of the interference from jammers and friendly signals that occupy the same signaling band.
