摘要

干涉测量的新趋势包括使用宽带系统作为精确测量角度或提高角度分辨率的手段。基于噪声信号频谱分析的超宽带干涉测量是基于两个间隔天线接收到的完全不相干噪声信号的总和。本文论述了更精确地估计运动目标的角度和角速度的技术。和信号的每个频谱分量在当前时间内以多普勒频率振荡。通过测量这些振荡的多普勒频率来估计运动目标的角速度。

Ultra wideband spectral interferometry

The new trends in the interferometry include the use of wide bandwidth systems as a means for accurate angle measuring or enhancing of angle resolution. Ultra wide band (UWB) interferometry with spectral analysis of noise signal is based on the summation of perfectly incoherent noise signals received by two space-apart antennas. This paper demonstrates techniques for more accurate estimation of the angle and the angle velocity of moving targets. Every spectral component of the sum signal oscillates in the current time with Doppler frequency. By measuring of Doppler frequency of these oscillations the angle velocity of moving target is estimated.
