Popis: We describe the implementation of a wavelet based transient detection algorithm and compare its performance with that of traditional Fourier techniques via a numerical simulation. The wavelet algorithm is a filter‐then‐detect algorithm; the filtering is accomplished in the wavelet transform domain by thresholding. The context is established by comparing the Fourier and wavelet transform in the signal processing setting. The performance of the wavelet filtering and Fourier‐based filtering as a part of the detection process on two simulated detection problems is compared using ROC curves.
