High Temperature Superconducting Filter Technology for Electronic Warfare Systems

Abstract

The modern battlefield electromagnetic environment is saturated with many microwave radar and communication signals. The density and sophistication of this environment makes it difficult for military electronic warfare (EW) systems to efficiently receive and respond to the microwave environment. Additionally, modern high duty cycle and frequency hopping emitters provide unique challenges to EW systems. The existence of only one of these modern emitters can easily saturate the receiver/processor — effectively blinding the system to potentially lethal threat systems. The potential of superconducting filter technology to this EW system problem will be discussed.
