Quantum Radar: Overview on Technology, Limitations and Opportunities

This paper encapsulates the fundamental operation of a Quantum Radar and demonstrates how entanglement can improve a radar’s signal-to-noise ratio. It focuses on the evolution of Quantum Radar technology by examining various types and bringing to light their unique characteristics. The paper also discusses the optimal radar type for various situations. Moreover, it thoroughly explores the properties of the Quantum Radar cross-section and compares it with the classical radar. Based on the research, finding covert targets and navigating through jammed environments are two key advantages of Quantum Radar. Finally, the paper discusses the limitations of each Quantum Radar type, along with future research directions.
