摘要
噪声遮盖性干扰是一种常用的干扰方法,高斯白噪声具有最佳遮盖干扰波形。提出了一种宽带高斯白噪声的产生方法,通过多路并行的M序列产生噪声数据,再经过系数可重新配置的多相滤波器,最后经过并串转换送给高速数模变换器。通过实测,产生了比较理想的宽带高斯白噪声,具有很好的实用价值。
Noise barrage jamming is a popular jamming technique and Gaussian white noise has the best barrage jamming waveform.This paper provides a generation method of wideband Gaussian white noise.The noise data is generated by M sequence of parallel multiple routes,then sent through multi-phase filter with reconfigurable factor,finally sent to high-speed digital to analogne cenverter after parallel-serial conversion.After practical test,satisfactory wideband Gaussian white noise is generated and it has excellent practical value.
