Summary:
Recent results that enable coherent communications and radar using chaotic waveforms are presented and discussed. Following the discoveries of chaos synchronization and control in the early 1990s, various engineering applications of chaos were envisioned. Novel communications technologies might use control to efficiently encode information in the symbolic dynamics of a chaotic oscillator, thereby exploiting the positive entropy for carrying information. Similarly, radar applications might exploit the positive entropy of a wideband, nonrepeating waveform for high-resolution imaging. As compelling as such applications are, subsequent development was hindered by the lack of a simple receiver that could compare favorably to standard correlation-based receivers. However, a new class of chaotic oscillators was recently reported that admit a linear representation and a simple matched filter. This development provides a coherent receiver to enable practical chaos communication and radar systems. Conceptual designs for both communications and radar using a matched filter for chaos are developed and considered.
