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 integrat-ed transmitter chip ADF7012 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 cod-ing function,comply with the design requirements,the system meets the need of the sounding data transmission.
