Radar in the quantum limit

IEEE International Symposium on Phased Array Systems and Technology, 2003., 2004
Deep space tracking radars, such as the Arecibo radar, have Terawatt class EIRP, and are the scale of a small village. As such it seems surprising that one would ask whether their performance is dictated by quantum theory. However in this talk we show that it is, due to the very large losses in link budget. In this talk we discuss the quantum limits of

Quantum Radar Cross Section

SPIE Proceedings, 2010
ABSTRACT The radar cross section C is an objective measure of the \radar visibility" of an objec t. As such, C is animportantconcept for the correct characterization ofthe o perational performance ofradar systems. Furthermore, C is equally essential for the design and development of steal th weapon systems and platforms.

Quantum Radar vs Noise Radar

2016 9th International Kharkiv Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves (MSMW), 2016
Preliminary results of the comparative analysis of Quantum Radar (QR) based upon quantum entanglement phenomenon and Noise Radar (NR) based upon classical coherence notion and correlation processing of random signals are presented in the paper. It has been shown that the basic idea of entangled multi-photon QR for simultaneous implementing of high ...

Quantum radar, quantum networks, not-so-quantum hackers

Signal Processing, Sensor/Information Fusion, and Target Recognition XXVIII, 2019
Many quantum technologies, such as quantum computers, rely on a phenomenon called entanglement. One reason why quantum networks are being studied is because they can distribute entanglement to their users. In this paper, we describe how quantum radars, particularly the recently-developed quantum two-mode squeezing radar (QTMS radar), can be used with ...

Microwave Quantum Radar: An Experimental Validation

2018 International Carnahan Conference on Security Technology (ICCST), 2018
We describe an experiment which comes very close to implementing a quantum radar based on entangled microwaves. A pair of entangled microwave beams are generated using a Josephson parametric amplifier (JPA) and measured by a pair of digitizers after amplification.

Determining the advantage of quantum radar

14th Pacific Rim Conference on Lasers and Electro-Optics (CLEO PR 2020), 2020
We discuss our progress towards creating a computer model of a quantum illumination type quantum radar. This will allow us to determine the quantum advantage from several important initial experimental demonstrations.

Opportunities and Challenges of Quantum Radar

IEEE Aerospace and Electronic Systems Magazine, 2020
It has been recognized for over half a century that quantum mechanics defines the ultimate limits for sensing devices, and products of that recognition are now on the horizon of practical implementation. One of the most promising of those products is quantum radar, which offers a capability to significantly improve the tradeoff between energy and ...

Quantum Noise Radar: Assessing Quantum Correlations

2019 IEEE International Conference on Microwaves, Antennas, Communications and Electronic Systems (COMCAS), 2019
We suggest overcoming the "Rayleigh catastrophe" and reaching superresolution for imaging with both spatially and temporally-correlated field of a superradiant quantum antenna. Considering far-field radiation of two interacting spontaneously emitting two-level systems, we show that for the measurement of the temporally-delayed second-order correlation ...

Quantum synthetic aperture radar

SPIE Proceedings, 2017
Synthetic aperture radar (SAR) uses sensor motion to generate finer spatial resolution of a given target area. In this paper we explore the theoretical potential of quantum synthetic aperture quantum radar (QSAR). We provide theoretical analysis and simulation results which suggest that QSAR can provide improved detection performance over classical SAR

A Quantum-Enhanced Radar Prototype

2019 IEEE Radar Conference (RadarConf), 2019
We have built and evaluated a prototype quantum radar in the laboratory which operates at microwave frequencies. Because the signal generation process relies on quantum mechanical principles, the system is considered to contain a quantum-enhanced radar transmitter.
