Multifunctional Radar and Communications Waveform Using Chaos

Multifunctional radar and communication systems possess advantages of lower cost and weight owing to sharing of hardware and antenna apertures. In addition, by using a joint waveform for both applications simultaneously, the occupied spectrum can be used very efficiently thereby guaranteeing a permanent availability of both functions. We propose a waveform implementation that utilizes properties from nonlinear dynamics and chaos to design a multifunctional waveform having the ability to adapt to varying operational and environmental considerations. In addition, use of a chaotic noise-like waveform has good low probability of intercept (LPI), low probability of detection (LPD), and anti-jam properties.
