摘要
简要介绍了自适应旁瓣对消的基本原理,推导出便于工程实现的理论公式。结合某型数字阵列雷达的研制,分析其特点。详细阐述旁瓣对消技术在数字阵列雷达中的应用方法,给出了理论仿真结果以及工程实现框图。
The basic principles of the adaptive sidelobe cancellation are simply introduced,and the theoretical formula for engineering implementation is deduced.The characteristics of digital array radars are analyzed with reference to the development of a certain type of such radar.The auxiliary antenna elements for sidelobe cancellation are all included and selected from the main radar＇s antenna elements,and used to form main beams at the same time.The application of the adaptive sidelobe cancellation technology in digital array radars is expatiated,and the simulation results and the block diagram of engineering implementation are given.
