Abstract
Two dimension convolution jamming algorithm is usually adopted to generate deceive jamming signal, but the real-time property is difficult to be realized due to the huge amount of calculation. Based on the CPCI framework, a jamming signal generator was designed by reasonably partitioning the system algorithm and mapping it to the hardware. The jamming signal was generated using 16 pieces of parallel DSP, and the parallel processing algorithm got almost 100% parallel efficiency. The designed system has been developed and manufactured. Laboratorial and external experiments have verified that the designed generator could generate two-dimensional false target jamming signal to interfere synthetic aperture radar (SAR) in real-time continuously.
