ARTINO（Airborne Radar for Three-dimensional Imaging and Nadir Observation）的3D成像和最低点观测原理使用分布在飞机整个机翼上的稀疏MIMO天线阵列。ARTINO原理的适应性，以高，快速飞行的飞机与大机翼需要新的概念，以处理PRF的限制。在本文中，扩展的ARTINO原则的基础上提出了两种不同的策略，即频率多样性和波形多样性。这两个概念都允许在任意机载平台上实现ARTINO原理。
The 3D imaging and nadir looking ARTINO (Airborne Radar for Three-dimensional Imaging and Nadir Observation) principle uses a sparse MIMO antenna array distributed over the whole wings of an airplane. The adaption of the ARTINO principle to high and fast flying airplanes with large wings requires new concepts to deal with PRF limitations. In this paper, an extension of the ARTINO principle is presented based on two different strategies namely the frequency diversity and the waveform diversity. Both concepts allow the implementation of the ARTINO principle to arbitrary airborne platforms.
