本文介绍了 2008 年至 2012 年期间频率 32 MHz 的超高能空气簇射无线电发射的一组测量结果。流星雨由地磁角和方位角选择,然后根据三个区间的能量选择:3*10^16 3*10^17 eV、3*10^17 6*10^17 eV 和 6*10^17 5*10^18 eV。在每个能量区间中,使用来自不同方向的天线的数学平均数据绘制平均横向分布函数。在本文中,利用实验数据确定了无线电信号平均幅度与地磁角、簇射轴距离和能量的关系。评估给定能量范围内宇宙射线簇射 Xmax 的最大深度。根据QGSJET模型计算和平均横向分布函数形状进行评估。
This paper presents the set of measurements of ultra-high energy air shower radio emission at frequency 32 MHz in period of 2008-2012. The showers are selected by geomagnetic and azimuth angles and then by the energy in three intervals: 3*10^16 3*10^17 eV, 3*10^17 6*10^17 eV and 6*10^17 5*10^18 eV. In each energy interval average lateral distribution function using mathematically averaged data from antennas with di?fferent directions are plotted. In the paper, using experimental data the dependence of radio signal averaged amplitude from geomagnetic angle, the shower axis distance and the energy are determined. Depth of maximum of cosmic ray showers Xmax for the given energy range is evaluated. The evaluation is made according QGSJET model calculations and average lateral distribution function shape.
