The design of X-band broadband linear array antenna used in electronic reconnaissance

介绍了X波段宽带电子侦察线性阵列天线设计方法,首先介绍线性阵列波束合成,然后给出仿真与实测结果,随后对结果进行分析,最后根据测试结果以及仿真结果得出结论。仿真结果显示天线性能良好,通过测试数据可以得出16个通道的副瓣电平在-15dB左右,通过计算所得0°移相和实际移相基本相吻合,以实测数据画出的天线波束图满足要求。

The design way of X-band broadband linear array antenna used in electronic reconnaissance is in troduced. The linear array beamforming is firstly introduced. Besides, the simulation result and test result are given, and then the result is analyzed. The conclusion is made in accordance with test result and simulation result finally. Simulation results show that the property of antenna is favorable, the minor level of sixteen channels is approximately -- 15dB according to test result, the zero degree dephasing is almost identical to realistic value, and a figure about antenna beam meets the requirements.
