巨型射电中微子探测阵列（GRAND）是一个计划中的大型超高能量宇宙粒子天文台，其能量超过108GeV。它的目标是解决长期存在的UHE宇宙射线起源之谜。为此，GRAND将探测到空前数量的UHE宇宙射线，并以无与伦比的灵敏度寻找未被发现的UHE中微子和与之相关的伽马射线。GRAND将使用大型天线阵列来探测由大气中UHE粒子引发的大面积空气阵雨产生的无线电发射。它的设计是模块化的：20个独立的子阵列，每个子阵列有10000个无线电天线，分布在10000平方公里以上。一个分阶段的建设计划将验证关键的探测技术，同时尽早实现重要的科学目标。在这里，我们提出了GRAND的科学目标、检测策略、初步设计、性能目标和建设计划。
The Giant Radio Array for Neutrino Detection (GRAND) is a planned large-scale observatory of ultra-high-energy (UHE) cosmic particles, with energies exceeding 108GeV. Its goal is to solve the long-standing mystery of the origin of UHE cosmic rays. To do this, GRAND will detect an unprecedented number of UHE cosmic rays and search for the undiscovered UHE neutrinos and gamma rays associated to them with unmatched sensitivity. GRAND will use large arrays of antennas to detect the radio emission coming from extensive air showers initiated by UHE particles in the atmosphere. Its design is modular: 20 separate, independent sub-arrays, each of 10000 radio antennas deployed over 10000 km2. A staged construction plan will validate key detection techniques while achieving important science goals early. Here we present the science goals, detection strategy, preliminary design, performance goals, and construction plans for GRAND.
