Research of the VLF atmospheric noise statistical prediction

摘要

The nature of the vlf atmospheric noise can have a dramatic effect on the performance of the vlf receivers. To understanding how the receivers will perform in different locations and time, the key is proper predicting the critical parameters of the vlf atmospheric noise. Based on the purpose, according to the historical data and the corresponding frequency and parameter variation chart, established the data fitting algorithm to predict the critical parameters of the vlf atmospheric noise. By simulating and comparing with the measured data, testified the effectiveness of the vlf atmospheric noise prediction method. To grasp the change rule of critical vlf noise parameters with time and geographical position is helpful to improve the vlf communication effectiveness.
