多波段可重构雷达接收机技术的研究

随着现代科学技术的迅猛发展及应用市场的迫切需求，现代雷达也出现了走向多功能综合一体化方向的趋势，用户希望在一部雷达上就能综合各种不同的功能，完成各种不同的任务，这就需要多波段工作的、可重构的雷达系统及多波段可重构雷达接收机。文中对各种不同的多波段接收机技术进行了分析，提出了一种新的多波段可重构雷达接收机结构，它不仅结构简单，可以全集成化，同时又能获得较好的性能。

Research on Multiband Reconfigurable Radar Receiver Technology

With the development of modem science technology and the emergent requirement of market, modem radar trends to the direction of muhi-function,flexility ,unification in one radar. The users hope to use only one receiver for various functions,all standards applications, it demands muhiband reconfigurable receiver. This paper discusses various architectures of multiband reconfigurable receiver for radars, and presents a novel muhiband reconfigurable receiver architecture suitable for a fully integration. its architecture is very simole, and can attain very good oerformance.
