Abstract: A wideband pulse detector and a method for operating the wideband pulse detector. The wideband pulse detector includes a signal collection unit for receiving electromagnetic pulses, a signal classification unit for classifying the electromagnetic pulses into N channels (where N is an integer of 2 or more) depending on frequency components corresponding to the electromagnetic pulses, a signal detection unit for detecting and holding the classified pulses, and a signal processing unit for converting the held pulses into digital signals, identifying types of the electromagnetic pulses corresponding to the converted digital signals using a classification algorithm, determining signal strengths of the electromagnetic pulses, and then controlling a reset circuit for successive signal detection.
