具有信道编码功能的气象探空数据发射机

Meteorological Sounding Data Transmitter with Channel Coding Function

探空数据通过无线电传输至地面,需要解决频道窄和干扰强的问题,采用低功耗单片集成发射机芯片ADF7012和超低功耗高性能单片机MSP430F2132,设计了一个具有4×4数据交织和CRC校验功能、载波频率可设置的探空数据发射机。测试结果表明,发射信号的频谱特性、发射功率和信道编码功能,符合设计要求,能满足探空数据传送的需要。

The sounding data is transmitted to the ground through the wireless network, which needs to solve the problems of channel narrow and strong interference. A sounding data transmitter which carrier frequency can be set is designed using the low power integrated transmitter chip ADFT012 and ultra low power and high performance microcontroller MSP430F2132, which has 4 × 4 data interleaving and CRC checksum function. The test results show that the functions such as spectrum characteristic, transmitter power and channel coding function, comply with the design requirements, the system meets the need of the sounding data transmission.
