In-lab validation of jammer detection and direction finding algorithms for GNSS
International Conference on Localization and Global Navigation Satellite System, 2019Our paper focuses on the detection and direction finding of jamming signals in Global Navigation Satellite System (GNSS)bands. A methodology for in-lab validation for three selected jammer detection algorithms and two selected jammer direction finding ...

A method of determining the bearing of a source of a sonar signal comprising determining the phase of a cyclic variation of the output signal of a sonar detector having a directional characteristic which occurs as the orientation of the detector, and hence its characteristic, is rotated.

Direction Finding of Linear Frequency Modulation Signal With Time-Modulated Array
IEEE Transactions on Antennas and Propagation, 2019This communication proposes a novel method for finding the direction of the linear frequency modulation (LFM) signal, which has a bandwidth that is much larger than that of the modulated frequency, based on the time-modulated array (TMA).

Direction Finding by Time-Modulated Linear Array
IEEE Transactions on Antennas and Propagation, 2018The direction finding method by the time-modulated linear array (TMLA) is analyzed and verified. The direction of arrival (DOA) can be calculated out by analyzing the spectrum characteristic of the received signal after the time modulation. Its principle

Direction finding in MIMO radar with large antenna arrays and nonorthogonal waveforms
Digit. Signal Process., 2019As an important research branch in multiple-input multiple-output (MIMO) radar, orthogonal waveforms are always desirable. In practice, however, the orthogonality may not be always guaranteed.

Direction findings on whistlers
Journal of Geophysical Research, 1959Efforts to study the direction of arrival and polarization of whistlers have led to confusion, presumably because of the complexity of the signals and their transient behavior. This letter describes one technique which shows promise in that it has given results on the direction of some whistlers.

THE art of navigating any mobile craft depends essentially on being able to determine the position of that craft with relation to a fixed point or points; the position may either be obtained in the form of a bearing on, and a distance from, any known fixed point, or of simultaneous bearings from two or more fixed points, which bearings are laid off on ...

Direction Finding of BPSK Signals Using Time-Modulated Array
IEEE Microwave and Wireless Components Letters, 2018A direction-finding algorithm by the time-modulated array (TMA) is proposed for binary phase shift keying (BPSK) signals. In the proposed scheme, only two antenna elements and a single RF channel are required, and the switch period has no relation with ...

RF-based Direction Finding of UAVs Using DNN
International Conference on Conceptual Structures, 2017This paper presents a sparse denoising autoencoder (SDAE)-based deep neural network (DNN) for the direction finding (DF) of small unmanned aerial vehicles (UAVs). It is motivated by the practical challenges associated with classical DF algorithms such as

Radioengineering
Bearing receivers are an important component of electronic warfare equipment, but their technical level today seems to be insufficient in a number of parameters. Aim of work – to create a receiver with a small unevenness of the frequency response, which significantly affects the bearing error.
