Definition of the Concept of an Interferometric Spectrum Analyser for the Detection of Frequency Hopping Radios

Abstract

The concept of a high resolution, large bandwidth and high dynamic range acousto-optic spectrum analyser for the detection of frequency hopping radios is described. The high resolution is achieved by selecting large time- aperture Bragg cells while the high dynamic range is obtained by using heterodyne detection in an interferometric structure. The large bandwidth is produced by a scanning process. An example of the probability of detection for a specific selection of parameters is given.
