Research on Calculation Method of Slope Range of GFE(L)1 Radar Based on Solar Method

文章介绍GFE(L)1型二次测风雷达利用太阳法开展距离探测的新型方式。该型号雷达通过探空气球中的GTS1型数字式电子探空仪发射的电磁波来进行距离探测。将太阳能替代探空仪作为信号,利用太阳噪声法计算得出L波段探空雷达在接收机中心频率1675 MHz接收到的太阳射电功率为-112.2 dBm,L波段二次测风雷达与探空仪有效通信距离为179.5 km,满足中国气象局探测中心的L波段(1型)高空气象探测系统业务操作手册技术指标中的150~200 km。

This paper introduces a new type of GFE(L)1 secondary wind radar which uses the solar method to carry out range detection.This type of radar carries out range detection through the electromagnetic wave emitted by GTS1 digital electronic radiosonde in the sounding balloon.In this method,the solar radiosonde is used as the signal,and the solar radio power received by the L-band sonde radar using the solar noise method at the receiver center frequency of 1675 MHz is^(-1)12.2 dBm.The effective communication distance between the L-band secondary wind radar and the radiosonde under this index is 179.5 km,which meets the technical index of 150~200 km in the L-band(type 1)upper-air meteorological detection system business operation manual of the China Meteorological Administration Detection Center.
