轻便式气球、火箭高空大气探测共用系统

A PORTABLE SHARING UPPER ATMOSPHERIC SOUNDING SYSTEM USED BY BOTH BALLOON AND MICRO-ROCKET

鉴于对高空大气探测日益增多的需求 ,而常用的接收、跟踪定位设备却比较笨重而且灵活性差 ,不能适应既需要机动灵活又能适合于多种场合使用的要求 .本文介绍通过提高接收系统的信噪比同时采用宽波束接收天线 ,研制了一套低成本、轻便式高空大气探测简便系统 .该系统调频发射机和高空大气探测有关仪器和地面抛物面接收天线、低噪声接收机及数据处理设备组成 .主要用于探空气球和微型火箭对高空大气探测数据的接收和处理 .

The requirements of upper atmospheric exploration systems are increasing, but usual receiving and tracking equipment are ponderous and with bad agility, and more and more unsuitable for multi-purpose situation which need more flexibility. A low cost portable upper atmospheric sounding system used by both balloon and micro-rocket is presented, which has much lower ratio of signal to noise and wider bandwidth. The system is composed of a frequency modulated transmitter, upper atmospheric sounding instruments, a wide beam parabolic receiving antenna on the ground, a receiver with low noise and data processing equipment. It is mainly used to receive and process the data from balloons and micro-rockets.
