摘要

摘要: 集成化已成为现代电子系统最重要的发展方向，雷达系统也是如此。现代直接变频技术具有成本极低、体积小、结构简单和高度集成化的特点，已广泛应用于通信市场，如手机、基站、卫星接收机和GPS接收机等，但至今未有在雷达中实际应用的报道。该文对直接变频技术在雷达中的应用进行了研究，特别是应用到相控阵体制的雷达上，能极大地降低雷达成本和体积，且有工作频带极宽、配置灵活、可重构的特点。因此，直接变频技术也将成为雷达技术的一个发展方向。该文最后给出了一个将直接变频技术应用到S波段相控阵雷达的设计实例。

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.
