摘要

我们提出了UHF和VHF地形电磁散射的机载实验观测，并演示了如何使用这种信号来确定目标高度。我们描述了到达时差(TDOA)处理，然后继续讨论如何使用多普勒信息来补充或取代TDOA处理。我们描述了两种这样的方法。第一种方法需要观察目标与其图像之间的多普勒分离，并进行反演以恢复高度。第二种方法利用多普勒域滤波面外能量，提高TDOA处理性能。

Experimental observation and modeling of overland height finding

We present airborne experimental observations at UHF and VHF of electromagnetic scattering from terrain and demonstrate how such a signal can be used to determine target height. We describe the time difference of arrival (TDOA) processing and then go on to discuss how Doppler information can be used to supplement or replace TDOA processing. We describe two such methods. The first entails observing the Doppler separation between the target and its image and inverting to recover height. The second method uses the Doppler domain to filter out-of-plane energy and improve the performance of TDOA processing.
