“…2) Noise characterization: By incorporating Wiener Filtering in the frequency domain, it is possible to target the removal of noise within specific frequency ranges [19]. Through Fourier Transform, we can obtain the spectral information of the signal and noise, including their power spectral densities and frequency distributions.…”

“…As the echoes from the main lobe are received by arrays in different spatial locations, exhibiting higher similarity than the sidelobe. DMAS introduces the spatial coherence of different channel data by multiplicative coupling in the beamforming process, which preserves the main lobe and suppresses the clutter interference [26][27][28]. DMAS has been further improved as lagbased DMAS (L-DMAS) [29], subarray average DMAS (SA-DMAS) [30], double-stage DMAS (DS-DMAS) [31], baseband DMAS (BB-DMAS) [32], etc.…”
