一种可编程视频噪声产生器

A generation technique for the programmable noise

可编程噪声源是现代自适应功率管理电子干扰系统中的重要部件。论文提出了一种以微处理器和数字电路为主构成的多路可编程噪声的产生原理和方法,它可对输出噪声分布、谱宽和幅度等参数实现动态管理,并且已经用于某些现代电子干扰系统中。

Modern electronic warfare (EW) systems demand a programmable noise source, which can generate controllable noise in its distribution and power spectrum. The generation technique for a programmable noise is described in the paper. The noise generator is con- structed by microprocessors and digital curcuits. The experimental results show that the noise generator can provide a noise signal with an expectable probability distribution, spec- tral width and magnitude.
