Problem Statement

An active sensing system probes the environment by transmitting a signal and processing the output of a receiver, which generally contains echoes from re ectors and boundaries, and also noise. Usually the transmission is pulsed. Delay between the transmission of a pulse and the moment when it returns to the receiver determines the distance to a target. Using a continuous periodic signal in transmission leads immediately to ambiguities and demasking. The scheme under consideration here transmits a continuous signal generated by a driven chaotic dynamical system, in an effort to reduce ambiguity and to increase robustness against noise.
