RF Steganography via LFM Chirp Radar Signals

Zhiping Zhang, / Yang Qu, / Zhiqiang Wu, / Nowak, Michael J. / Ellinger, John / Wicks, Michael C.

A novel radio frequency (RF) steganography scheme is proposed to hide digital communication in linear frequency modulation (LFM) radar signals. This joint radar/communication waveform serves two purposes simultaneously: it performs as the original radar waveform, and it provides a covert communication to legitimate receivers. The proposed RF steganography scheme hides digitally modulated communication information inside an LFM radar signal to prevent enemy from detecting the existence of such hidden information via a new modulation and variable symbol duration design.
