一种全空域球面相控阵天线对非协同目标的过顶跟踪方法

A Passing Zenith Tracking Method for Non-cooperative Target with Spherical Phased Array Antenna in Hemispherical Coverage

针对天线对非协同目标过顶跟踪时天线角跟踪动态过大的问题,提出了一种应用于全空域球面相控阵天线的角跟踪方法。应用该方法,在球面阵天线对非协同目标的整个跟踪过程中可实现角跟踪系统全程低仰角跟踪,从而避免了球面阵天线在对目标跟踪过程中出现的高仰角过顶跟踪的问题。该方法在航天或航空测控领域有广泛的应用前景。

For the problem of excessive angular tracking dynamic characteristics of the antenna when the non-synergistic target is tracked by the antenna at its zenith,an angular tracking method for the spherical phased array antenna in hemispherical coverage is proposed.By applying this method,low elevation angle tracking can be realized for the angular tracking system during the entire tracking process of the spherical array antenna to the non-synergistic target,thereby avoiding overhead tracking problem in the high elevation angle of the spherical array antenna that occurs during the target tracking process.The method has a wide application prospect in aerospace or aeronautical telemetry,tracking and control(TT&C)field.
