Abstract

A new-generation radiosonde working in L band for weather measurement is presented. The radiosonde consists of a phase-locked FM receiver mainly constructed of ICs and a FM/FSK transmitter implemented with the combination of microstrips and surface mounted components. Although the cost is low, excellent performance, especially narrow bandwidth, high sensitivity and stability under drastic change of temperature are achieved. Field experiments show that the new radiosonde may entirely replace the pulsed type of radiosonde currently being used in P.R. China to obtain more reliable meteorological information and save more spectrum resources
