Research on One New Blanket Jamming Technology and Tactics

The efficiency of broad band barrage Stand-Off Jamming (SOJ) is decreased quickly with such techniques as radar ultra-low sidelobe antennas and narrow-channel filter. In allusion to this situation, the weakness of SOJ and Electronic Counter-CounterMeasure (ECCM) of modern radar against blanket jamming are analyzed firstly. Then, a blanket Stand-Forward Jamming (SFJ) method with close-in mainlobe jamming tactics and coherent phase jamming technique is suggested to apply. This paper puts forward a principle block diagram of the jammer and designs jamming mode and signal in detail as well. Furthermore, it investigates the characteristics of power and time-frequency of this jamming technique. Computer simulation indicates that this jamming technique is superior to broad band barrage SOJ.
