A short review of the receiving-mutual-impedance method (RMIM) for mutual coupling compensation in direction finding applications using linear array is conducted. The differences between the conventional-mutual-impedance method (CMIM) and RMIM, as well as the three different determination methods for receiving mutual impedance (RMI), will be discussed in details. As an example, direction finding with better accuracies is used for demonstrating the superiority of mutual coupling compensation using RMIM.
Resonance based radar target recognition using the extinction pulse (E-pulse) technique was first implemented in the mid 1980s. Various derivatives of the E-pulse technique itself as well as the associated problems of identification and differentiation have been reported throughout the literature. In this paper a modified version of the E-pulse, termed the "banded" E-pulse technique is introduced as an alternative tool for target identification.Index Terms-Electromagnetic scattering, extinction pulse (E-pulse), resonance based target identification, singularity expansion method (SEM), ultrawideband radar.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
