ambiguity function

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.

However, in calculating the range nominal resolution of rectangular pulse signals using conventional definition formula, quadrature operation for range ambiguity function or infinite integration for "SIN" function is required.

然而，对矩形脉冲信号来说，按常规定义式计算距离名义分辨力，需要距离模糊函数的积分运算或对正弦函数进行无穷积分，这些积分运算往往较为复杂或为不定值；

The PN code has a 'good' ambiguity auto-correlation function like Delta function and correlation flow measurement can avoid direct time counting.

伪随机码具有优良的双值自相关函数特性，其形状类似冲激函数，而相关测量避免了对微小时间的直接测量。

The multi-period ambiguity function of LFMCW radar signal is given, and compared with single-period ambiguity function.

给出了LFMCW雷达信号的多周期模糊函数，并与单周期信号进行了比较。

The method , based on cross-ambiguity function, is more suitable for time delay estimation in low SNR.

这种基于互模糊函数的算法与传统的直接互相关法相比, 更适用于低信噪比情况下的时差估计.
