Abstract: PURPOSE: An ES(Electronic Warfare) received and a noise signal filtering method using the same are provided to filter an interference wireless communication signal by automatically controlling a threshold value in real time. CONSTITUTION: A signal analysis device(30) receives a digital pulse line type signal from a signal receiver. The signal analysis device identifies a threatening signal by analyzing the threatening signal. If interval between the signal pulses is less than the set time, the signal analysis device sets a noise flag. The signal analysis device determines the distribution rate of the noise flag in the set pulse line. The distribution rate is greater than a level limit setting value. The signal analysis device controls a signal level set in the signal receiver.
