Abstract:

Clandestine signals are transmitted by using a surface wave acoustic device to disperse the spectrum of a pulse-modulated CW carrier. The dispersed signal is itself modulated and then transmitted to a remote location, at low level. At the remote location, an acoustic device of conjugate characteristics is used to recover the dispersed signal from out of the background noise. Author
