Chaos in optimal communication waveforms [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 The properties of nonlinear dynamics and chaos are shown to be fundamental to optimal communication signals subject to two practical and realistic design requirements: (i) operation in a noisy environment and (ii) simple hardware implementation. Starting with a simple electronic circuit, a linear filter receiver is presumed, and the matched optimal ...

Constrained Transmit Beampattern Design Using a Correlated LFM-PC Waveform Set in MIMO Radar
Sensors, 2020 This paper considers the design of a desired transmit beampattern under the good ambiguity function constraint using a correlated linear frequency modulation-phase coded (LFM-PC) waveform set in multiple-input-multiple-output (MIMO) radar. Different from

Time Reversal Detection for Moving Targets in Clutter Environments
Remote Sensing, 2023 Moving target detection plays a pivotal role in many applications, especially in radar systems. In addition, time-reversal (TR) technology can improve radar detection probability by effectively solving the problem of multipath signals. However, detection

Optimal Waveform Selection for Robust Target Tracking [PDF]
Journal of Applied Mathematics, 2013 This paper proposes a new optimal waveform selection algorithm for intelligent target tracking. In radar systems, optimal waveform is inspired by the improvements in performance. When the target is intelligent and tries to escape from detection, it will maximize the estimation error to degrade the target tracking performance.
