Based on the features of ambiguity function of lfm signal , a new adaptive kernel is given 然后,基于线性调频信号模糊度函数特征,提出了一种新的自适应核函数。
Wideband ambiguity function ( waf ) is the powerful tool to analyze the wideband signal , and it is also coherent to cwt 宽带模糊度函数是宽带信号分析的有力工具,它与连续小波变换也是内在一致的。
The basic theory of wideband signal processing is discussed and presented . the coherence among cwt , wcp and waf is pointed out emphatically 论述了宽带信号处理的基本理论,指明了连续小波变换与宽带相关处理、宽带模糊度函数的一致性。
Two kinds of typical wideband signal , frequency modulation ( fm ) signal and frequency spread signal , is analyzed qualitatively with wideband ambiguity function 以宽带模糊度函数为工具定性地分析了两类典型宽带信号,即调频信号和频率分集信号。
Using the non - sensitive characteristic of ambiguity function method ( afm ) regarding cycle slips , it is sufficiently exerted the characteristic of genetic algorithms which are optimization for ambiguity solution on - the - fly . 5 利用模糊度函数法对于周跳不敏感的特点,充分发挥遗传算法的优化搜索特点,以实现对载波相位整周模糊度的在航解算。
