Research and Design on Signal with Broadband Continuous Chaotic Waveform

According to the LPI requirement of the modern battlefield signal,this paper researches the broadband continuous chaotic signal with LPI and the detuned coupling type Colpitts broadband chaotic circuit,analyses and compares different coupling type of Colpitts oscillator circuits.The paper also analyses the continuous chaotic waveform signal which are generated by chaotic circuit,and the ambiguity function image of this chaotic signal is simulated at last.The result of the simulation shows that the signal basis distribution is even,and the shape is similar as thumb pin.It has such characteristics as better range resolution and rate resolution,and has higher noise rejection capability.
