In this article the advanced modeling and simulation of narrow band waveguide diplexer for radio-relay links at 13 GHz is presented. Three different electromagnetic simulation packages were used for design of diplexer with 0.76% of fractional bandwid

The wave returning from a human torso in radar measurements is affected by the characteristics of the abdomen with respect to the thorax. While the physical properties affect the magnitude of the reflected components from each part, the motion delay

This paper describes the different considerations and challenges in measuring human cardiopulmonary radar cross section (RCS). The effect of clutter on the received signal is explained as well as the importance of preserving baseband dc content for v

The radar cross section (RCS) corresponding to human cardio-respiratory motion is measured for a subject in two different recumbent positions. Lying face-up (supine), the subject showed an RCS of 0.326 m(2). But when lying face-down (prone), the RCS
