Abstract:Dense false-target jamming can implement effective blanket jamming on radar. This kind of jamming can make radar too busy to process true target, even bring on the saturation of radar signal processing. Time-delay and overlap-add techniques or convolution technique can produce dense false-signal, nevertheless they consume more resource. A new method for producing dense false-signal— compartmentalization and regroupment is proposed in the paper. This method does not include multiplication operation that needs more time and storage. It is related only to pulse width and has nothing to do with the number of false targets. Simulation and experiment results have proved the validity of this method.
