Researching the Generation Method of Digital Noise Source

摘要

In electronic warfare, noise is a significant jamming source. Using the high speed DSP technology, the generation method of digital noise is researched in this paper. The Gauss white noise is created with iterative computation. By modulating the digital noises with varieties of signals, the noise-jamming sources, corresponding to the signals, are obtained. The simulation experiments show that the created noise-jamming source has an overlay effect on the spectrum of the spot signal, i. e. that, it has a good jamming effect.
