摘要
本文从连续子波变换和子波级数的性质及子波的框架理论出发，推导了时间尺度域的匹配滤波器形式，理论分析表明它的理想性能和匹配滤波器相同．然后将它应用于未知参数的瞬态信号检测，给出了例子、模拟结果和性能分析，表明了它的有效性和鲁棒性．
A kind of matched filters in time-scale domain has been investigated in this paper based on continuous wavelet transforms, wavelet series and frame theory. It is shown that the wavelet based methods provide the same performance as traditional matched filters in ideal condition. Then we use it to detect transient signal with unknown parameters. Numerical examples and performance analysis show the method is effective and robust.
