摘要

本文介绍了一个安装在风扰动海面上的测试目标的低掠掠角前向散射的超宽带雷达测量的实验描述和数据示例。测量雷达采用亚纳秒发射脉冲(0.15 ns, 3 dB脉冲宽度)，中心频率为9 GHz，在距离维度上达到2 cm的分辨率。这个分辨率足以完全解决直接和多路径(单和双反弹)对信号反射的贡献，从塔上安装的复古反射器。该几何图形为前向散射提供了标称的3度掠掠角。双极化数据的例子，采取了各种风条件，突出的变化幅度和散射分量的位置随时间的变化。

Measurements of ocean forward scatter with an ultrawideband radar

This paper presents an experiment description, along with data examples, for ultrawideband radar measurements of low grazing angle forward scatter associated with a test target mounted above a wind disturbed sea surface. The measurement radar used subnanosecond transmit pulses (0.15 ns, 3 dB pulsewidth) at a 9 GHz center frequency to achieve resolutions as fine as 2 cm in the range dimension. This resolution was sufficient to fully resolve direct and multipath (both single and double bounce) contributions to the signal reflecting from a tower mounted retro reflector. The geometry presented a nominal 3 degree grazing angle for forward scatter. Dual polarized data examples, taken for a variety of wind conditions, highlight changes in the magnitude and the location of the scatter components with time.
