The temperature-measuring radio-acoustic sounding system combined with wind profile radar to measure atmospheric temperature at heights of 100—1500 m is developed and its precision is 0.5K. The system is controlled by chip microprocessor 8031 and can transmit standard sinusoidal waves with various frequencies and arbitrary time intervals according to various requirements. The device has a compact structure and it is completely designed on one printed circuit card, which is directly plugged in the expanding groove of personal computer (PC). It mainly contains CPU (chip microprocessor 8031), four-channel 12-bit D/A converters and four-channel sinusoidal wave generators. When working smoothly, the system can receive orders from personal computer (PC) at any time, and then radio-acoustic signals can be transmitted out via isolated circuit, outside connected power amplifier and loudspeaker.
