Abstract

Operational reliability has been shown to be a useful measure of the effectiveness of a radar's detection algorithm in a specific operational scenario. Operational reliability transforms traditional detection theory parameters into a metric that can be combined with component reliability, thus setting the foundation for the formulation of a radar's total reliability. Component reliability can be divided into two main areas of study: lifetime prediction and degradation characterization. The former focuses on the component's mean-time-to- failure (MTTF), while the latter investigates the slow decrease of a component's performance throughout its lifetime until the component eventually fails. In this paper, we explore the degradation of common radio frequency (RF) components that are used in a radar system. The degradation of the components is then used in conjunction with the radar's operational reliability to develop a model for the overall reliability of a radar system.
