This article covers the following comparison of measurements vs. analysis for receiver dynamic range metrics in a phased array hybrid beamforming architecture. A commercially available 32-channel development platform is used to validate the analysis with measurements. The receiver analysis for subarray beamforming is reviewed, with an emphasis on handling the differences between signal gain and noise gain at the point where signals are combined in the analog subarray. An analysis is shown for the development platform receiver performance and compared against measured results. A summary of the results is discussed with the intention to provide a measured vs. modeled reference point that can be leveraged to predict the performance of larger systems.
The next generation of MILCOM platforms will need to leverage more modern communication technologies that have been developed to enable commercial platforms such as cell phones and Wi-Fi.
This article compares the benefits and challenges of three common receiver architectures: a heterodyne receiver, a direct sampling receiver.
This article reviews the strengths and weaknesses of two electronic beamforming techniques: phase shifters (PSs) and true time delays (TTDs).
