The well-known classical pulse radar has several disadvantages. The high transmitted peak power can be easily detected and warn an enemy, and the ambiguities in both range and Doppler measurements lead to problems with unambiguous localization and tracking.

Detection of radar echoes in noise revisited
IEEE Transactions on Information Theory, 1966The analysis of radar detection probability in the presence of unknown parameters, given by Kelly, Reed, and Root for maximum-likelihood detection procedures, is extended in this paper to cases where the detection procedures still belong to the class of maximum-likelihood procedures, but the actual waveform, or noise covariance, or both, may differ ...

The noise characteristics of radar receivers
Journal of the Institution of Electrical Engineers - Part IIIA: Radiolocation, 1946The various quantities which determine the performance of radar receivers are discussed. Most of the effort towards improvement has been concentrated on securing the lowest possible noise-factor in amplifiers and mixers and this is the main theme of the paper.

Design of a Noise Radar Demonstrator
2016 17th International Radar Symposium (IRS), 2016The NATO SET-225 Research Group is planning a series of live trials of Noise Radar technology to be performed in summer, 2016 at the Fraunhofer FHR Institute in Wachtberg (near Bonn). The preliminary architecture of the Demonstrator to be used in these trials is described starting from aims and requirements and arriving to define the main system ...

2006 International Radar Symposium, 2006
A noise radar system consisting of an array of K transmit antennas and M receive antennas is considered. Two implementations are considered: in the first, a single noise source is, after appropriate phase shifting, transmitted; in the second approach K independent noise sources are transmitted.

Radar cross-sectional study using noise radar
SPIE Proceedings, 2015A noise radar system is proposed with capabilities to measure and acquire the radar cross-section (RCS) of targets. The proposed system can cover a noise bandwidth of near DC to 50 GHz. The noise radar RCS measurements were conducted for selective targets like spheres and carpenter squares with and without dielectric bodies for a noise band of 400MHz ...

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 ...

Estimating Correlation Coefficients for Quantum Radar and Noise Radar: A Simulation Study
2019 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2019For target detection, quantum two-mode squeezing (QTMS) radars and noise radars require estimation of a covariance matrix. A scalar function of the covariance matrix is then used for deciding the presence or absence of a target. In this paper, estimation of the covariance matrix is carried out by minimizing the Frobenius norm between the sample ...

On the theory of noise Doppler radar
IGARSS 2000. IEEE 2000 International Geoscience and Remote Sensing Symposium. Taking the Pulse of the Planet: The Role of Remote Sensing in Managing the Environment. Proceedings (Cat. No.00CH37120), 2002Presently, there is an increasing interest in noise modulated radar in a wide spectrum of applications, such as surveillance, tracking, altimetry, and sub-surface profiling. Wide-band signals with high range resolution, reduced ambiguities and high ECCM performance can be achieved. In this paper, the theory of noise modulated radar is treated.

Radar tomography using MIMO noise radar and antenna with beam synthesis
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014Conventional SAR generates 2D image using combination of range compression and 1D aperture synthesis. The range resolution of such approach is determined by the signal spectrum width, while cross-range resolution is defined by the synthetic aperture length.
