在干扰和箔条杂波同时存在的电磁环境中,如何使雷达正常工作一直是困扰雷达研究人员的一大问题。本文设想采用costas序列和Barker码的组合信号构成一种新的雷达体制,可望能有效地同时抗御这两种干扰。文中按给定条件对各类信号逐一比较,最后确定选择第四类信号作为抗干扰波形,并给出信号产生和处理的系统框图,同时指明新体制雷达的现实意义和生存能力。 In the electromagnetic environment where interference and chaff clutter coexist, how to make the radar work normally has always been a major problem for radar researchers. In this paper, a combination of costas sequence and Barker code is used to construct a new radar system, which is expected to be able to effectively resist both these two kinds of interferences simultaneously. In this paper, according to the given conditions, the signals of all kinds are compared one by one. Finally, the fourth type signal is selected as the anti-interference waveform, and the system block diagram of signal generation and processing is given. At the same time, the realistic significance and survivability of the new system radar are indicated.
