The effect of radar signal construction on detectability

摘要

Three spread spectrum radar signals with similar power spectral densities are analyzed using cyclostationary signal processing techniques. It is shown that squaring these signals yields information about the carrier frequencies, chip rates and hop frequencies. It is also shown that, in an environment that contains additive white noise, increasing the number of frequencies used to construct the signal decreases the detectability of the sub-pulse frequency spectral lines.
