机动式空馈相控阵测量雷达结构误差的分析

Analysis about the Structure Error of the Mobile Optical-Feed Phase-Array Measure Radar

空馈相控阵雷达的馈源与天线相互分离,二者之间存在很高的相对位置精度要求。而这种相对位置关系容易受到各种因素的影响,从而降低雷达测量精度,对于机动式精密测量雷达这种影响尤为显著,因此必须对这些误差因素进行分析并尽可能减小其影响。文中以某大型机动式空馈相控阵测量雷达为例分析了影响该类雷达测量精度的各种结构误差,并提出了相应的解决措施。

The feed and antenna of the optical-feed phase-array radar are separated from each other, and the relative position requests high accuracy, which is easy to be influenced by various factors, thus reduce radarb measure precision. For mobile accurate measure radar, the influences are more serious. So these factors causing error must be analyzed to reduce their effects by all means. With a large mobile optical-feed phase-array measure radar as example, this paper analyzed different structure errors which influenced the measure precisions of the radar, and put forward corresponded solutions to reduce the effects of these errors.
