A modulated impulse generating apparatus includes a source signal generator that generates a source signal, a first oscillation unit that, when activated, a signal having extracts a desired frequency component from the source signal generated by the source signal generator and causes amplitude of the extracted signal to increase, a second oscillation unit that, receives input of a signal caused to increase by the first oscillation unit, and that, when activated, causes amplitude of the input signal to increase together with the first oscillation unit and outputs a modulated impulse modulated wave, and an activation unit that activates the first oscillation unit after the source signal generated by the source signal generator has been input to the first oscillation unit and activates the second oscillation unit after a certain time period has elapsed and oscillation amplitude of the input signal has increased.
