中文摘要:
      介绍了一种在菲涅耳区测量雷达散射截面(RCS)的方法。通过近-远场变换,利用目标的一维距离像、二维逆合成孔径雷达(ISAR)像数据估计目标RCS,避免了太赫兹(THz)频段RCS测量不容易满足远场条件的困难。采用强散射点提取技术剔除支架等背景噪声对测量结果的影响,提高了RCS估计精确度。利用该方法对0.14 THz雷达缩比测量数据进行处理,获得了典型目标在P波段的RCS估计值。
英文摘要:
      Customary Radar Cross Section(RCS) measurement using far-field or compact ranges is limited due to an increasing difficulty to produce plane wave illumination as the frequency grows higher. An image-based technology for predicting far-field RCS from monostatic near-field measurement is developed. Furthermore, RCS estimation accuracy is improved by decreasing the background noise of the target zone, such as trestle table. At last,sample data sets of 0.14 THz target echo are collected to produce P-band RCS of aircraft carrier.
