本文在研究信号和噪声的Lipschitz奇异性的基础上,提出了通过小波变换估计信号奇异性来估计时域天线阵波达时间的新方法。因为小波变换能很好地处理奇异性,所以本文为多年来一直未能解决的超宽带时域天线阵列波达时间估计提供了一个新的途径。最后,本文以二元天线阵列为例,给出了分析计算结果,并与相关法的结果进行了比较,表明该法是非常有效的。 In this paper, based on the Lipschitz singularity of signal and noise, a new method to estimate the time-domain of the antenna array by wavelet transform is proposed to estimate the signal singularity. Because wavelet transform can deal with singularity well, this paper provides a new approach for UWB time-domain array time-of-arrival estimation which has been unresolved over the years. Finally, this paper takes the binary antenna array as an example, gives the analysis and calculation results, and compared with the results of the correlation method, shows that the method is very effective.
