Ranging With Electromagnetic Singularities

Abstract

Most improvements in radar have concentrated solely on the temporal characteristics of the electromagnetic pulse. The spatial dimension is typically exploited only through arrays of antennas. The limits to using spatial characteristics of a transmitted beam to perform ranging were investigated, specifically, Laguerre-Gaussian beams as potential carriers for encoding range in spatial characteristics. The results indicate that whereas the beams are indeed capable of encoding range, aberrations and imaging fidelity limit the utility of the approach to small ranges. The system is better suited for microscopy than it is for battlefield ranging.
