In this paper, a new Chaotic Pulse Position and Phase Coded Pulse Compression Radar (CPPPC PCR) signal is studied.
结果表明:自相位调制不影响混沌信号脉冲的形状,但能产生非线性相移使混沌信号频谱展宽;
Self-phase modulation of fiber does not affect the pulse shape of chaotic signal, however, its product of nonlinear phase shift can widen the chaotic signal spectrum.
