Effects of fast Fourier transform window size on the target strength spectra of tungsten carbide spheres

The window size (WS) of the fast Fourier transform (FFT) is one of the important parameters when calculating target strength (TS) spectra from broadband echo waveforms. However, the effects of the FFT WS on TS spectra have not been thoroughly investigated. Before studying fish echoes, we thus focuse...
