Introduction to Noise Radar and Its Waveforms [PDF]
Sensors, 2020 In the system-level design for both conventional radars and noise radars, a fundamental element is the use of waveforms suited to the particular application. In the military arena, low probability of intercept (LPI) and of exploitation (LPE) by the enemy

On the Analysis of PM/FM Noise Radar Waveforms Considering Modulating Signals with Varied Stochastic Properties [PDF]
Sensors, 2021 Noise Radar technology is the general term used to describe radar systems that employ realizations of a given stochastic process as transmit waveforms. Originally, carriers modulated in amplitude by a Gaussian random signal, derived from a hardware noise

Noise Radar Technology: Waveforms Design and Field Trials. [PDF]
Sensors (Basel), 2021 Performance of continuous emission noise radar systems are affected by the sidelobes of the output of the matched filter, with significant effects on detection and dynamic range. Hence, the sidelobe level has to be controlled by a careful design of the transmitted waveform and of the transmit/receive parts of the radar.

Bistatic noise radar: Demonstration of correlation noise suppression
IET Radar, Sonar & Navigation, 2023 In this study, spatial separation of the radar transmitter and receiver units is considered, as a means of reducing the masking effect in noise radars.

Low-PAPR Waveforms with Shaped Spectrum for Enhanced Low Probability of Intercept Noise Radars
Remote Sensing, 2021 Noise radars employ random waveforms in their transmission as compared to traditional radars. Considered as enhanced Low Probability of Intercept (LPI) radars, they are resilient to interference and jamming and less vulnerable to adversarial exploitation

Quantum-enhanced noise radar [PDF]
Applied Physics Letters, 2019 We propose a protocol for quantum illumination: a quantum-enhanced noise radar. A two-mode squeezed state, which exhibits continuous-variable entanglement between so-called signal and idler beams, is used as input to the radar system. Compared to existing proposals for quantum illumination, our protocol does not require joint measurement of the signal ...
