在过去的70年里,各种雷达系统使用越来越复杂的处理技术对冰冻圈的许多不同组成部分进行了成像。这些系统使用不同的脉冲长度、信号频率,在某些情况下还使用调制信号。雷达系统日益多样化,可能会因使用不一致的术语而造成混淆。在这里,我们概述了最先进的雷达技术,并建议使用一个简化和统一的术语供冰冻圈社区使用。我们建议使用与目标无关但指定信号特征的术语。根据这一建议,穿透地下的商用脉冲系统应称为探地雷达(GPR),脉冲雷达称为无线电回波探测(RES)。连续波(CW)雷达系统应称为探地连续波雷达。我们还建议使用描述符来表示系统的任何附加特征,这些描述符指定安装系统的平台(例如机载)或频率范围(例如高频(高频))或调制(例如调频(调频))。
Over the past 70 years, many different components of the cryosphere have been imaged with a variety of radar systems using increasingly sophisticated processing techniques. These systems use various pulse lengths, signal frequencies and, in some cases, modulated signals. The increasing diversity of radar systems has created the potential for confusion due to the use of non-consistent terminology. Here we provide an overview of state-of-the-science radar technologies and suggest a simplified and unified terminology for use by the cryosphere community. We recommend a terminology that is target independent but specifies the characteristics of the signal. Following this recommendation, commercial impulse systems that penetrate the subsurface should be referred to as ground-penetrating radar (GPR), and pulse radars as radio-echo sounding (RES). Continuous-wave (CW) radar systems should be referred to as ground-penetrating CW radars. We further suggest any additional characterisation of the system be expressed using descriptors that specify the platform it is mounted on (e.g. airborne) or the frequency range (e.g. HF (high frequency)) or modulation (e.g. FM (frequency modulated)).
