On the Optimal Positioning of Antennas in the Microwave Personnel Screening System with Inverse Synthetic Aperture

Abstract

In this paper we consider strategies of positioning of antennas in a new type of microwave personnel screening system, in which the motion of the subject in the vicinity of an antenna array could be used to create synthetic aperture required for obtaining high resolution radar images. For this purpose we simulate 2D point spread functions (PSF) of the screening system depending on the number of receive and transmit antennas in a horizontal section of the viewing geometry. Optimization is considered to find how positioning of a fixed number of transmit and receive antennas can improve PSF of the perspective radar system.
