A quantum synthetic aperture radar image denoising algorithm based on grayscale morphology

open access: yesiScience
Summary: The quantum denoising technology efficiently removes noise from images; however, the existing algorithms are only effective for additive noise and cannot remove multiplicative noise, such as speckle noise in synthetic aperture radar (SAR) images.

Quantum Radar and Noise Radar – Overview and Performance Evaluation

open access: yesTechnium Electro
Both Noise Radar (NR) and Quantum Radar (QR), with alleged common features, aim to use the randomness of the transmitted signal to enhance radar covertness and to reduce mutual interference. While NR has been prototypically developed and successfully tested in many environments by different organizations, research and development investments on QR did

Fundamental aspects of netted radar performance [PDF]

open access: yes, 2010
Netted radar employs several spatially distributed transmitters and receivers for information retrieval. This system topology offers many advantages over traditional monostatic and bistatic systems which use a single transmitter and a single receiver ...

Quantum illumination advantage in quantum Doppler radar

open access: yes
A Doppler radar is a device that employs the Doppler effect to estimate the radial velocity of a moving target at a distance. Traditional radars are based on a classical description of the electromagnetic radiation, but in principle their performance can be improved employing entangled quantum probe states. For target detection, i.e. hypothesis testing,

Research on Direct Detection Method and Performance of Single-photon Counting Terahertz Radar

open access: yesLeida xuebao
The conventional terahertz radar suffers from limited operation range for long-distance, noncooperative target detection due to the low transmitter power and atmospheric attenuation effect, both of which pose a hindrance in meeting the requirements of ...
