SAR++: A Multi-Channel Scalable and Reconfigurable SAR System

SAR++ is a technology program aiming at developing know-how and technology needed to design the next generation civilian SAR systems. Technology has reached a state, which allows major parts of the digital subsystem to be built using custom-off-the-shelf (COTS) components. A design goal is to design a modular, scalable and reconfigurable SAR system using such components, in order to ensure maxi...

Experimental estimation of local SAR in a multi-transmit system

Introduction: SAR management is a widely discussed topic at main fields of 3T or above, particularly in the framework of multi-transmit systems [1,2]. Typically, local SAR is estimated via patient model simulations, i.e., extensive numerical calculations not suitable for clinical routine. An alternative way to estimate local SAR might be given by “Electric Properties Tomography” (EPT), i.e., th...

State Dependent Multi channel Queuing System with Ordered Entry

In the present study, we analyze the multi-channel service system with ordered entryfrom finite-source and finite-storage at each channel. The arrival and service rates are assumedto be state dependent. The steady state probabilities of the system are obtained by usingChapmann-Kolmogorov equations. Some other performance indices viz. utilization of servers,expected number of units in the system...

An algorithm of frequency estimation for multi-channel coprime sampling

In some applications of frequency estimation, it is challenging to sample at as high as Nyquist rate due to hardware limitations. Based on conventional ESPRIT, a new method for frequency estimation with double-channel sub-Nyquist sampling is proposed. When the two undersampled multiples are relatively prime integers, partial samples are selected to estimate the frequency components contained in...
