Digital Reform Design of Sonde for Radar

摘要

This paper mainly introduces the scheme and the implement method about digitally rebuilding sonde for radar by using kinds of sensor, including three aspects content below:Firstly, raise a master plan that design digital sonde by using SCM(Single Chip Micyoco); The sonde which is in weather radar is primarily used to measure three primary data: temperature, humidity and atmospheric pressure, and then send the data in telegraph code by responder. Several problems will be solved by digital reform of sonde, which include how to choose temperature device, humidity device and atmospheric pressure device, the design of signal transformation circuit, telegraph code signal generation, the design of output circuit etc. Secondly, introduce the hardware circuit design and the implement method of rebuilding sonde. Thirdly, introduce the software design and implement method of sonde, including the process and source program.
