Study on Quantum Radars for Space Applications

The need for improved and reduced integration time for detection in radars has led researchers to develop quantum radars. Quantum Radars use the concepts of quantum mechanics, like quantum entanglement and quantum illumination to give enhanced results in detection with reduced integration time. Quantum Radars have found applications in various fields like - aerospace, biomedical imaging, and civilian. This paper primarily focuses on the novel design of a quantum antenna that is capable of simulating the phenomena of quantum entanglement. It also gives a concise idea about Quantum radars by providing a comparison to the classical radars and a simple simulation of a quantum antenna that can be used to create the phenomena of quantum entanglement.

I. Introduction

As studies on quantum mechanics grew, researchers stumbled upon quantum entanglement and illumination, and its ability to enhance the detection abilities of a classical radar. Experiments have shown that the quantum radar's ability to detect objects with a reduced integration time proves to outperform the classical radars by a significant amount and can easily replace the classical radars in operation. Intense research has led us to understand that the enhancement of quantum illumination over classical illumination was limited to theoretical considerations and the practical implementations will require the resolution of multiple issues. It also has been seen that the theoretically simulated levels of enhancement cannot be recreated in the practical world because the entanglement not being as strong as seen in theory.
