Binary offset carrier modulation is a type of new modulation method whose main point is to pre-modulate non-modulated spread spectrum base-band signal with square wave to incur energy spectrum splitting so that the new signal’s spectrum could be isolated from the original one.Due to its great potential in high-precision code tracking and multi-path interference elimination

Chaotic signals that result from chaotic dynamical systems are the families of stochastic signals.They are sensitive to initial conditions and look like “noise” in time domain.Because of the noise-like feature,chaotic signals usually occupy a wide bandwidth in frequency domain.Wideband chaotic signal is an ideal signal in radar system for its noise-like behavior and good self-correlation
