Digital realization of pull-off jamming in R-V dimensions

One method can be implemented in FPGA for multi-deceptive targets pulling-off jamming both in range dimension and velocity dimension is proposed. In range dimension, the whole protected scope is covered through multiple FIFOs connected in series and the pulling-off on range tracking gate is done with a uniform delay control on all deceptive targets. In velocity dimension, multi-Doppler frequencies distributed in possible scope modulated on the same one range target and one modulating DDS module carries out the velocity pulling-off. Particular, one “expansion DDS” module generates the Doppler modulating coefficients which featured feasibility, general purpose and expansive capability. Field experiments have proved the validity of this method.
