Spectrogram radar clutter removal
WebThe amelioration of sea clutter effects is intimately tied up with STC. For normal targets, as underlined by the radar equation, we have seen that the returned signal power varies according to 1/R4. However, the sea does not act like a normal target, as its effective RCS varies according to range.
