摘　　要：受机载电子干扰吊舱空间尺寸的限制,对吊舱有限空间内安装的阵列天线提出了较高的设计要求。针对试验任务特点,提出了吊舱前后视渡越跟踪天线、收发全双工两维电扫阵列天线、天线与射频信道一体化的设计思想,该方法较好地解决了阵列天线增益与吊舱空间受限的矛盾,提高了对低空大射程目标实时测控的连续性、有效性和可靠性。论述了阵列天线的体制,阐述了收发共面相控阵天线结构、功耗和安装角度,通过仿真分析和测试,验证了该方法的可行性和有效性。Due to the space limitation of airborne electronic jamming pod,high design requirements are proposed for the array antenna installed in the space-limited airborne jamming pod.In consideration of the characteristics of the test mission,a design idea is proposed,which involves tracking switching between front-view and rear-view antennas,full-duplex two-dimensional electric sweep and integration of antenna and RF channel. The conflict between the antenna gain and the space limitation can be better solved by this method.And consequently,the continuity,effectiveness and reliability of real time measurement and control of low altitude and largerange targets are improved.In this paper,the system principle of phased array antenna,as well as the structure,power consumption and installation angle of Tx/Rx coplanar phased array antenna are analyzed. Finally,the feasibility and effectiveness of the method are verified by both simulation analysis and experiment.
