Assessing Spectral Compatibility Between Radar and Communication Systems on Measured Data

Abstract

Radar operation in a spectrally dense environment is nowadays a very challenging problem due to the increasing demand of spectral resources for defense/surveillance applications, remote sensing capabilities, and civilian wireless services. This paper explores the technical feasibility of radar waveforms capable of ensuring spectral coexistence with overlaid radiators via a modern digital Arbitrary Waveform Generator (AWG). To this end, a specific hardware-in-the-Ioop test bed is designed to mimic the perception-action cycle necessary for the agile management of the available radio spectrum. Then the AWG synthesized waveform is measured with a Spectrum Analyzer (SA) in order to demonstrate its compliance with the spectral constraints forced by the design algorithm as well as its fidelity with the computer simulated theoretical counterpart.
