论文摘要
我们开发了一种无线电干涉技术，用于观察由宇宙颗粒引发的广泛空气淋浴。在这项原理学研究中，我们表明，可以直接地以高精度得出广泛的空气淋浴的性能。当可以在$ \ sim $ \ sim $ 1 NS之间达到不同接收器之间的时间同步时，在淋浴深度上，$ <0.2^\ circolution $ <0.2^\ circolution的方向重建分辨率最大为$ <10 $ g/cm $^2 $，可以在研究的完整参数范围内获得，甚至更高的准确性范围的临时方向。此外，通过将开发的方法应用于繁殖天线的致密阵列，可以显着降低无线电检测的能量阈值。所提出的方法可以纳入操作和未来的宇宙粒子天文台，并且具有高精度，它具有在揭开超高能量宇宙粒子磁通量的组成中起着至关重要的作用。
We developed a radio interferometric technique for the observation of extensive air showers initiated by cosmic particles. In this proof-of-principle study we show that properties of extensive air showers can be derived with high accuracy in a straightforward manner. When time synchronisation below $\sim$1 ns between different receivers can be achieved, direction reconstruction resolution of $< 0.2^\circ$ and resolution on the depth of shower maximum of $<10$ g/cm$^2$ are obtained over the full parameter range studied, with even higher accuracy for inclined incoming directions. In addition, by applying the developed method to dense arrays of radio antennas, the energy threshold for the radio detection of extensive air showers can be significantly lowered. The proposed method can be incorporated in operational and future cosmic particle observatories and with its high accuracy it has the potential to play a crucial role in unravelling the composition of the ultra-high-energy cosmic-particle flux.
