... realization. The Fourier space imple- mentation of the matched filter requires the computation of the DFT of the echo, N pointwise multiplication of DFTs of the probing and received signals, and an inverse ... DFT of the product of the two DFTs. Jointly these tasks require N(1 + 2log 2 N) multiplications. The Zak space implementation of the matched filter req...
