多功能相控阵雷达发展现状及趋势

Development Status and Trend of MPAR

多功能相控阵雷达(MPAR)是一种高性能相控阵雷达,一部MPAR就可以实现多部传统雷达才能实现的功能,从而大大降低了使用和维护成本,是雷达发展过程中的一项重大进步和创新。文中首先分体制、产品和波段3个方面介绍了MPAR的发展现状;然后,分析了MPAR关键技术,如射频模块技术、子阵列集成技术、多波束形成技术、双极化技术、MI-MO技术等;最后,指出了MPAR的发展趋势。

Muhifunctional phased array radar （MPAR） is a type of high performance phased array radar. MPAR is an important ad- vance and innovation in radar development course, the reason for which is that only one MPAR can fulfill all the functions that must be implemented by multiple conventional radars with greatly reduced use and maintenance cost. Status of MPAR is introducedin in terms of system, product, and band. Then, key technologies of MPAR are analysed, such as RF module technology, sub-array inte- gration technology, multi-beam forming technology, dual-polarization technology, MIMO technology, et al. Finally, Future develop- ment trend of MPAR is pointed out in this paper.
