متن کاملAutonomous Spoofing Detection and Mitigation with a Miniaturized Adaptive Antenna Array
The performance of a spoofing detection and mitigation technique that makes use of the directions of arrival (DOAs) information about the navigation signals has been assessed. The directions of arrival have been estimated by utilizing a miniaturized antenna array developed for the reception of Galileo navigation signals of the public regulated service in E1 and E6 frequency bands. The performan...
متن کاملA Soft-Input Soft-Output Target Detection Algorithm for Passive Radar
Abstract: This paper proposes a novel scheme for multi-static passive radar processing, based on soft-input soft-output processing and Bayesian sparse estimation. In this scheme, each receiver estimates the probability of target presence based on its received signal and the prior information received from a central processor. The resulting posterior target probabilities are transmitted to the c...
متن کاملComparative Analysis of Two Approaches to Joint Signal Detection, ToA and AoA Estimation in Multi-Element Antenna Arrays
In this paper two approaches to joint signal detection, time of arrival (ToA) and angle of arrival (AoA) estimation in multi-element antenna array are investigated. Two scenarios were considered: first one, when the waveform of the useful signal is known a priori and, second one, when the waveform of the desired signal is unknown. For first scenario, the antenna array signal processing based on...
