Abstract
When the radio communication of an armed squad fighting in a jungle is interfered with by enemy’s radio jamming equipment and their command and intelligence cannot be transmitted and exchanged, are there any other communication methods that can be used to solve such an emergency and covert communication problem? Focusing on this problem, a camouflage covert communication method (CCCM) in air is proposed by imitating cricket’s sound. As well-known, there exist all kinds of animals’ sounds in the jungle; however, hearing these animals’ sounds, people generally considers them as background noise and ignores them. Based on this fact, the proposed CCCM uses the cricket’s sound as the carrier wave, imitates the features of the cricket’s call sequence to construct the camouflage communication sequence, and utilizes the time interval (TI) between two adjacent pulses to encode information. Meanwhile, other animals’ sound is superimposed to the camouflage communication sequence to improve the camouflage ability of the generated communication sequence. Experimental results are provided to demonstrate the performance of the proposed CCCM.
