Devising an Optimal Time-Delay Circuit Configuration for a Microwave-Photonics-Based Radio Communication Jammer

Abstract

Elaborating the previously proposed new concept for the design of a radio communication jammer, which consists in replacing a multichannel digital electronic processor with an ultra-wideband optoelectronic processor, in this paper, we propose and investigate an advanced time delay processing circuit based on an optical Mach-Zehnder interferometer. Comparative analysis with the previous version shows near than three order of magnitude a decrease in the length of the optical fiber required to destruct the radio channel for transmitting the command code, which significantly improves size, weight, and cost characteristics of a jammer, and reduces its response time.
