Abstract

Abstract

Integration has become the most important development direction of modern electronic system, and so is radar system. Modern direct-conversion technology has the characteristics of low cost, small size, simple structure and high integration. It has been widely used in the communication market, such as mobile phones, base stations, satellite receivers and GPS receivers, etc. But up to now, there has been no report of practical application to radar. This paper studies the application of direct-conversion technology to radar, especially to phased array radar, which can greatly reduce the cost and volume of radar, and has the characteristics of wide working frequency band, flexible configuration and reconfiguration. Therefore, direct-conversion technology will also become a development direction of radar technology. Finally, a design example of applying direct-conversion technology to S band phased array radar is given.
