研究非线性调频信号波形设计方法。 依据相位逗留原理，采用动态优选法，给出了一种改进的非线性调频信号波形设计方法。
To study the method of designing nonlinear frequency modulation (NLFM) signal waveform, the dynamic selection method was adopted on the basis of phase stationary theory.
利用相应的高层次模型，详细分析并仿真了电流源匹配误差和电流源输出阻抗对DAC的非线性误差nl、信号噪声失调比SNDR、无杂波动态范围SFDR的影响。
With corresponding models how the matching errors and output resistance of current source affect the NL, SNDR and SFDR of DAC is analyzed and simulated in detail.
它的分解基是随动态信号波形的变化而变化 ，具有自调节自适应的特征 ，因此能在时频域内描述非平稳非线性信号的局部特性。
Since the decomposition bases can vary with the local features of dynamic signals, the method is adaptive , therefore, highly efficient for describing nonlinear and non?stationary signals.
