The Generation Of Chaotic Radar Signal Based On FM Network

MIMO radar and Opportunistic array radar require multiple transmit signals while orthogonalwaveforms and controllable spectrum. It must be synchronized between these multiple signals. Inradar systems, it is difficult to transmit multiple synchronous signals directly to receiver. Usuallymultiple transmit signals can be synchronization by a small control signal.Based on self-feedback FM system, this paper focuses on the discussion of a FM network chaoticsystem and adaptive coupled synchronization control. as an example using self-feedback FM chaoticsystem with double coupling, the system output two orthogonal Chaotic signals, The chaotic signalspossess a flat broadband spectrum structure, show approximate ideal “thumbtack” ambiguity function,are easy control of statistical properties and its trajectory,Main works and innovations of this thesis are as follows:1. A new self-feedback FM chaotic system is designed, which can generate two chaotic signalsand has coupling before its feedback. Simple dynamic analysis is given in the linear and nonlinear condition.2. A two self-feedback FM system is extended to a multiple self-feedback FM system, whose dynamic behaviors are analyzed in the different control parameters.3. Research and analysis of output signal generated by the self-feedback FM chaotic system aregiven. An adaptive synchronization controller is proposed to synchronize the self-feedback FM chaotic systems from FM code by the coupling information of phase and frequency.4. Design adaptive synchronous controller by the phase and frequency coupling information. UseFM code to realize drive synchronous of the frequency modulation system.
