Abstract
To solve the problem that the operating range of a ground TT&C equipment is limited by the line of sight,an air-based TT&C data relay equipment can be used. For air-based TT&C 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 de-signed PAA satisfies about 130 km and 2 Mbit/s telemetry data relaying,thus solving the problem of range TT&C for low altitude targets.关键词
