【摘要】 本文所设计的新型温度探空仪是由温度感应元件、测量振荡器、付载波振荡器、发射振荡器、电源和外壳组成。温度感应元件为MF52型珠状热敏电阻,采用脉宽法测温,整个电路大都采用了CMOS集成块。该新型温度探空仪具有温度信息取样率高(50次/秒)调制信号与付载波完全同步、同相及体积小、重量轻、价格低等点特。更多还原

【Abstract】 A new prototype tmperature radiosonde was designed and tested in the laboratory. It was composed of a bead thermistor, audio oscillator sub-carrier oscillator,UHF oscillator battery and an assembling box.The main feature of RS design is that the pulse-width and temperature change relationship was used instead of the conventional thermistor resistance and freguency change relationship. In laboratory tests,relatively high data accuracy and high sampling rate were observed. The radiosonde is compact, light weight and fundamentally solid-state constructed,更多还原
