| 摘 要： | 雷达系统的精确校准是保证地海杂波测量数据可靠性的关键问题.本文利用地面有源雷达校准器(ARC)对L波段HH极化机载杂波测量雷达进行绝对校准,通过ARC设计、目标提取以及坐标系变换技术,充分考虑了校准场地背景杂波、载机姿态和GPS误差等因素对雷达系统常数、时延和天线方向图的影响.分析结果证明了这一技术的有效性.

| Abstract: | Exact calibration of radar systems is an important problem to ensure the data reliability of the terrain and sea clutter measurement.This technique calibrates the L band HH polarized airborne clutter measurement radar absolutely with active radar calibration (ARC) on the ground.The effects of background clutter,airplane postures and GPS errors on system constant,time delay and antenna pattern are considered carefully by means of design of RCS,signal extraction of ARC and a set of coordinate transforms.The validity of this method is proved by the analysis results. |
