Abstract
A weak signal detection device for detecting a weak signal appearing intermittently with a level that is less than or equal to internal noise of a radio frequency (RF) receiving part may comprise: a cross-correlation spectrum processing part configured to generate a cross-correlation spectrum using a correlation between RF receiving channels; and a waveform combiner configured to generate an output spectrum having a spectrum persistent function by assigning weight values to a current waveform and a previous waveform of the cross-correlation spectrum.
