】介绍了一种用于单通道单脉冲自跟踪体制的新型Ｓ波段四单元短背射式自跟踪天线系统。单元天线为以“十”字交叉振子为辐射器的宽频带、高增益改进型短背射天线，天线阵采用菱形布阵，馈电网络为微带集成电路构成的单通道单脉冲和差形成网络，系统增益＞２３ｄＢ，大于２０％带宽内的电压驻波比＜１．５，差波束零深＜－３０ｄＢ，左右旋零点不一致≤０．１°，半功率波瓣宽度为１０°，天线质量≤１５ｋｇ。
A new S-band four-element short-throw self-tracking antenna system for single-channel monopulse self-tracking system is introduced. The unit antenna is a wide band and high gain improved short back-shot antenna with a “ten” cross dipole radiator. The antenna array adopts a rhombus array, and the feeding network is a single-channel single-pulse and poorly formed microstrip integrated circuit Network, system gain> 23dB, VSWR <1.5 in bandwidths greater than 20%, zero depth <-30dB for differential beams, inconsistent ≤0.1 ° left-handed rotation null, half-power lobe width 10 °, Quality ≤ 15kg.
