A Data Record and Analysis System for a guidance Radar based on 51 family series MCU has been designed in this article. The function of this system is detecting the control and guide capability of the Radar. The hardware of this system is made of by 4 parts. They are the data acquisition module, the data storage module, the data transmission module and the simulating signal source module. Considering the application system has the extract demands such as the reliability and volume to the test system, an airborne data acquisition system based on MCU has been designed to count the real time gathering circuit. Under the environment to the data storage of the airborne equipment, an application system with 1MB storage capacity based on MCU has been designed. We have also designed the data transmission module to transfer the data into computer. There is a conversion interface in this module which has the function of swapping data between MCU and computer. The simulating signal source module can take out several analog and digital Radar command signal. It has offered a useful method to check the ability of the equipment. Radar command processing program has been designed in the software system and we take Lab Windows/CVI6.0 as developing tool in this part. After the data have been translated from airborne system to the computer on the ground, we have also finished the targets which is include of statistical the radar data, removing the disturbing data and analysis radar command data by using the technology such as DDE. In the same time we bring forward a new algorithm to judge the control accuracy of the radar. By the way we have accomplishing the task of effective data storage, printing testing reports and characteristic curve etc to the result. The application system we have developed has offered the important support to the examination of radar performance. It helps the engineering technical personnel to get the true command data of radar under the condition of existing a great deal of disturbance data. Therefore it offered a technique to enhance the ability of modernization to our national defense in this field. The software and hardware system have been used for half a year in an army. The system is very stability and all the parameters accord the design requirement
