The main work of this paper is to design the corresponding parabolic antenna measurement system software, the paper focuses on the development of the parabolic antenna and error measurement system of data processing and display software. Parabolic antenna is one of the most commonly used. The composition generally has reflector, the antenna support, strengthen tendons and so on. Parabolic antenna measurement needs for a complete driver program design. And show measurement results and calculation program. Measurement principles are based antenna parabolic antenna measuring overall system block diagram, from both hardware and software to build a parabolic antenna measuring system. Hardware design, including microprocessor controlled stepper motor, the antenna measurement amplifier circuit design and data collection. Software components including the microprocessor control program, microcontroller and the serial communication between the host computer and receive data processing module, and finally design visualization software measurement. Parabolic error evaluation software development is a systematic project involving meter placement method, the number of measurement points and error relations, surface fitting, reconstruction model and the standard model matching, error evaluation, functional plannin
