摘要
开展了数字相控阵雷达天线发射多波束的基础研究工作:首先阐述了发射多波束的基本工作原理,研制开发了数字相控阵雷达发射同频多波束的测试系统,并对发射多波束工作状态下天线的基本特性(如驻波特性和波瓣特性等)进行了研究和测试,通过实测数据与仿真结果的对比,验证了发射多波束的正确性和可行性,为数字阵列相控阵雷达未来的发展,实现雷达/电子干扰/通讯等同时多功能、共口径提供了技术支持。
Foundational research work of digital phase array radar is developed in this paper. Principle of transmitting multi-beam is expounded. The schematic diagram of measurement system is presented, and characteristics such as VSWR and beam of antenna array are tested. The results of measurement are in good consistence with those of simulation, which confirms the correction and feasibility of transmitting multi-beam. It is helpful for the technical support of the development of digital phase array radar to realize multi-function( radar/electronic interference/communication) with the same aperture.
