A spread spectrum technique using noise-modulated waveforms is proposed for covert communications. The noise key and the noise-like modulated signal are transmitted over orthogonal polarisations to mimic unpolarised noise. The received signals are mixed together to accomplish demodulation. Excellent bit error rate performance is achieved even under adverse propagation conditions.
