SAR measurement for different antenna configurations

SAR Measurement Procedure for Multi-antenna Transmitters

This paper proposes and verifies a SAR measurement procedure for a multi-antenna transmitter that requires the measurement of two-dimensional electric field distributions for the number of antennas and the calculation for obtaining the three-dimensional SAR distributions for arbitrary weighting coefficients of the antennas prior to determining the average SAR. The proposed procedure is verified...

Measurement-Based Evaluation of the LTE MIMO Downlink at Different Antenna Configurations

Multi-antenna transmission modes are an integral feature of the 3GPP LTE downlink. While these modes are well defined in the standard there are no restrictions on the choice of transmit and receive antennas. In order to investigate the impact of the basestation antenna configuration on the LTE open loop downlink, a measurement campaign, comparing horizontally and vertically spaced antenna confi...

Performance Analysis for Bistatic Interferometric SAR Configurations

The results of an interferometric performance analysis for spaceborne parasitic SAR configurations are presented. The analysis includes errors due to limited SNR, block adaptive quantization, range and azimuth ambiguities, and geometric decorrelation for both flat surfaces and random volumes. Relative height accuracies for three spaceborne configurations with PALSAR, ASAR and TerraSAR-X as illu...
