摘要

中国的火星探测器“天文一号”将在2020年7月至8月的火星发射窗口期间发射,其中包括一个轨道飞行器和一个登陆探测器。被选为火星车有效载荷之一的是地下穿透雷达模块(RoSPR)。RoSPR的主要科学目标是表征火星土壤的厚度和亚层分布。RoSPR由两个通道组成。RoSPR的低频通道将穿透火星土壤至10至100米的深度,分辨率为几米。更高频率的通道将穿透到3到10米的深度,分辨率为几厘米。本文介绍了仪器的设计和一些现场试验结果。

The Mars rover subsurface penetrating radar onboard China's Mars 2020 mission

China's Mars probe, named Tianwen-1, including an orbiter and a landing rover, will be launched during the July-August 2020 Mars launch windows. Selected to be among the rover payloads is a Subsurface Penetrating Radar module (RoSPR). The main scientific objective of the RoSPR is to characterize the thickness and sub-layer distribution of the Martian soil. The RoSPR consists of two channels. The low frequency channel of the RoSPR will penetrate the Martian soil to depths of 10 to 100 m with a resolution of a few meters. The higher frequency channel will penetrate to a depth of 3 to 10 m with a resolution of a few centimeters. This paper describes the design of the instrument and some results of field experiments.
