Abstract : An impulse interference suppression circuit for use in combination with an N-pulse Moving Target Indicator system comprising a gate connected to block the output signal from the MTI system when energized, and a circuit for taking the magnitudes of successive echo return signals, subtracting the magnitudes of consecutive echo signals to remove clutter, comparing the consecutive difference signals from such substractions against each other, and generating and applying a blocking signal to the gate if the difference between the subtraction difference signals is above a given threshold level.
