我们认为，将一个高功率、大口径的雷达发射机与几个大口径接收阵列相结合，制成地球空间雷达--一种能够探测从对流层上层到太阳日冕的近地空间的雷达--将改变地球空间研究。我们回顾了20世纪60年代非相干散射雷达的出现，作为一种媒介，将地球空间早期的开创性研究统一在一个共同的理论、实验和仪器框架中，并建议地球空间雷达将对未来空间气象研究的发展产生类似的影响。然后，我们讨论无线电阵列技术的最新发展，这些技术可用于开发与目前使用的雷达相比具有新的或显著改进的能力的地球空间雷达。综述了具有新的和改进的能力的地球空间雷达的一些应用，包括流星回波、中间层和平流层湍流、电离层流动、等离子体层和电离层不规则性以及太阳日冕和日冕物质抛射的反射。最后，我们对技术要求进行了总结。
We argue that combining a high‐power, large‐aperture radar transmitter with several large‐aperture receiving arrays to make a geospace radar—a radar capable of probing near‐Earth space from the upper troposphere through to the solar corona—would transform geospace research. We review the emergence of incoherent scatter radar in the 1960s as an agent that unified early, pioneering research in geospace in a common theoretical, experimental, and instrumental framework, and we suggest that a geospace radar would have a similar effect on future developments in space weather research. We then discuss recent developments in radio‐array technology that could be exploited in the development of a geospace radar with new or substantially improved capabilities compared to the radars in use presently. A number of applications for a geospace radar with the new and improved capabilities are reviewed including studies of meteor echoes, mesospheric and stratospheric turbulence, ionospheric flows, plasmaspheric and ionospheric irregularities, and reflection from the solar corona and coronal mass ejections. We conclude with a summary of technical requirements.
