摘要

本文介绍了一种用于大气科学研究应用的数字接收机的特点。数字接收机在位于印度Gadanki的国家大气研究实验室(NARL)的MST(中间层-平流层-对流层)雷达模拟接收机上进行了初步测试验证。本文简要介绍了NARL的科研活动,MST雷达系统二十年来的技术开发活动,用于大气参数估计的雷达接收机的特点,数字接收机的规格和硬件细节,模拟信号数字接收机的性能测试方法。此外,还给出了利用MST雷达实现数字接收机后得到的大气风廓线。这些数字接收机现在与1.28 ghz低大气风廓线、53 mhz MST雷达和30 mhz HF雷达的导频有源阵列一起工作,以估计地球大气不同高度的大气参数。

Indian MST radar digital receiver first results
In this article we explain the features of a Digital Receiver developed for atmospheric science research applications. The digital receiver is initially test validated with an analog receiver of MST (Mesosphere-Stratosphere-Troposphere) Radar located at NARL (National Atmospheric Research Laboratory), Gadanki, India. This article presents a brief overview of NARL scientific research activities, two decades of technological development activities of MST Radar system, radar receiver features for estimation of atmospheric parameters, specifications and hardware details of digital receiver, performance test methods of digital receiver with simulated signals. Furthermore, an atmospheric wind profile obtained after implementing the digital receiver with MST Radar is presented. These digital receivers are now operational with 1.28-GHz lower atmospheric wind profilers, pilot active array of 53-MHz MST Radar and 30-MHz HF radar developed at NARL to estimate atmospheric parameters at different height levels of Earth's atmosphere.
