Millimeter wave noise radar technology
Third International Kharkov Symposium 'Physics and Engineering of Millimeter and Submillimeter Waves'. MSMW'98. Symposium Proceedings (Cat. No.98EX119), 2002We present the main results of theoretical and experimental development of the NRT (noise radar technology) for the MM waveband which has been studied at the Laboratory of Nonlinear Dynamics of Electronic Systems (LNDES) of the Institute of Radiophysics and Electronics, National Academy of Sciences of Ukraine since 1990.

Dedicated applications of Noise Radars
2015 16th International Radar Symposium (IRS), 2015a novel approach for design of Radar sensor for shot range applications based upon Noise Radar Technology is presented. This radar technology relies on transmitting of wideband noise/random signals and coherent processing of radar returns. We have carried out experiments on generation of 2D and 3D tomographic imaging using Ka-band continuous waveform ...

Radar Noise Jamming Calculations Simplified
IEEE Transactions on Aerospace and Electronic Systems, 1981The ratio of radar jamming noise power to radar thermal noise power (J/N) is examined in a multiple noise jammer environment where jammer distances and energy levels vary. A simpler form of the computation of J/N is shown for several practical multiple noise jammer configurations.

Phase noise analysis in distributed coherent noise radar systems
2008 International Radar Symposium, 2008Noise radars, providing near thumbtack auto ambiguity signals, allow for fine resolution of targets in range and Doppler measurements. Both correlation processing as well as spectral interferometry require coherence, so the transmitters and receivers must be driven by highly stable oscillators as phase noise introduced into the system degrades the ...

Chaos Generators for Noise Radar
2009We present results of top-down design of chaos generators that are based on nonlinear electronic systems. Several types of chaotic waveform generators are described such as Weak Resonant BWO, multi-mode resonant systems, time-delayed circuits of ring and reflection feedback types, etc.

Evolution of Quantum Radar Concept to Noise Radar Concept
IEEE Aerospace and Electronic Systems Magazine, 2020Preliminary results of the comparative analysis of quantum radar (QR) based upon quantum entanglement phenomenon and noise radar (NR) based upon classical coherence and correlation processing of random signals are presented in this article. Common and distinguishing features of NR and QR are briefly discussed.

Noise radar detection optimized for selected targets
2017 18th International Radar Symposium (IRS), 2017This paper presents a technique for detection of selected targets in the context of ultrawideband noise radar. The technique applies to scenarios where targets can be modeled as having a few predominant scatterers, such as some made man-made targets. The basic idea is to change the signal used as reference for detection in such a way that it is adapted

Monopulse-radar angle tracking in noise or noise jamming
IEEE Transactions on Aerospace and Electronic Systems, 1992In many monopulse radars, feedback in the angle-tracking servo system is taken to be directly proportional to the monopulse ratio. In those radars, monopulse measurements are conditioned on simultaneous occurrences of receiver sum-channel video exceeding a detection threshold: if a detection fails to occur, the measurement is ignored, and the angle ...
