为了在线性调频雷达信号中隐藏数字通信，提出了一种新的射频隐写方案。这种联合雷达/通信波形同时服务于两个目的：它作为原始雷达波形执行，并向合法接收器提供隐蔽通信。提出的射频隐写方案通过一种新的调制和变码时长的设计，将数字调制的通信信息隐藏在LFM雷达信号中，防止敌人发现隐藏信息的存在。
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.
