Redstone Technical Test Center (RTTC) is a Department of Defense (DoD) Electromagnetic Environmental Effects (E3) test facility. RTTC facilities include a suite of amplifiers, antennas, and instrumentation that are used to perform E3 tests on military as well as commercial platforms. As more and more wireless communication and control systems are added to military platforms, system interoperability...
In this paper the performance of the ESPAR (electronically steerable passive array radiator) antenna in suppressing both the co-channel and inter-symbol interferences is compared with the conventional circular and linear arrays. For this purpose, the STAP (space-time adaptive processing) is implemented in both arrays with equal elements. Simulation results show that when the pattern of the ESPAR antenna...
This paper investigates the effective gain of antennas in indoor channels. A metric called instantaneous effective gain is proposed, and a multiple-cluster 3D channel model is used to facilitate the proposed antenna effective gain. In the multiple-cluster channel model, Laplacian and double exponential distribution are utilized to model azimuth and elevation signal power distribution respectively,...
