摘要
空基测控中继是为解决地面测控设备作用距离受视距限制的问题而提出的,而相控阵天线是空基测控中继设备的技术难点。根据实际需求,提出了相控阵天线的设计方案,对阵列形式、天线的流形、阵元间距、阵列规模以及阵元形式等进行了详细设计,并对天线的接收发射性能进行了仿真,对跟踪控制技术途径进行了阐述。所设计的相控阵天线增益可以满足约130 km、2 Mbit/s遥测数据中继,解决远距离低空飞行目标的靶场测控问题。
To solve the problem that the operating range of a ground TTC equipment is limited by the line of sight,an air-based TTC data relay equipment can be used.For air-based TTC data relay equipment,the technical difficulty is focused on the phased-array antenna（PAA）.According to pratical requirement,a PAA design scheme is proposed. The details,such as the array from,antenna flow pattern,array element spacing,array scale,element form and so on,are designed. At the same time,the T/R performance of the antenna is simulated,and the technical pathway of tracking and control is described. The gain of the designed PAA satisfies about 130 km and 2 Mbit/s telemetry data relaying,thus solving the problem of range TTC for low altitude targets.
