Accurate single-observer passive coherent location estimation based on TDOA and DOA
Chinese Journal of Aeronautics, 2014 This paper investigates the problem of target position estimation with a single-observer passive coherent location (PCL) system. An approach that combines angle with time difference of arrival (ATDOA) is used to estimate the location of a target ...

Wind farm interferences in Passive Coherent Location
2013 International Conference on Radar, 2013Rapid growth in the number of wind farms may influence the performance of many radar systems. The radar echoes originating from wind turbine's blades and tower may mask existing objects or generate false plots. In the presented paper the authors analyze the influence of a wind turbine on Passive Coherent Location radars and discuss the effectiveness of

Options of disrupting surveillance of Passive coherent locator
2017 International Conference on Military Technologies (ICMT), 2017Passive surveillance systems are working on Passive coherent locator principle and are new perspective of air-surveillance. This paper is following basic PCL principles and proposes the key points for successful interference of PCL signal processing to disrupt right work.

Digital beamforming for Passive Coherent Location radar
2008 IEEE Radar Conference, 2008The paper presents digital beamforming for Passive Coherent Location (PCL) radar. The considered circular antenna array is a part of a passive system developed at Warsaw University of Technology. The system is based on FM radio transmitters. The array consists of eight half-wave dipoles arranged in a circular array covering 360deg with multiple beams ...

Passive coherent location matched filter alternative
2017 IEEE Radar Conference (RadarConf), 2017This paper introduces an alternative method to traditional matched filtering for PCL applications. The developed method adapts the filter structure rather than the underlying signal of the surveillance channel. This allows for minimization of interference or noise present in the surveillance channel that are correlated or uncorrelated with the ...

Track-to-track fusion for passive coherent location
2018 37th Chinese Control Conference (CCC), 2018In order to address the problem of track-to-track fusion in passive coherent location (PCL) system, where the cross-covariance of errors of local estimates is unavailable, an information-theoretic criterion based a fast fault-tolerant generalized convex combination with memory (IT-FFGCCwM) fusion algorithm is proposed.

DVB-T2 passive coherent location radar
2016 IEEE NW Russia Young Researchers in Electrical and Electronic Engineering Conference (EIConRusNW), 2016In this paper, an overview of the passive coherent location radar utilizing transmitter of signals of the second generation digital terrestrial television DVB-T2 standard as an illuminator of opportunity is presented. The radar antenna is designed as an 16-element phased antenna array. The signal reception and analog-to-digital conversion are performed

Autonomic subsystems for cognition in Passive Coherent Location
2010 IEEE Radar Conference, 2010In a previous paper [1] we mentioned that Passive Coherent Location (PCL) can be thought of as Cognitive Radar[2]. The deployment of PCL systems (also known as Passive Bistatic Radar-PBR) is fraught with difficulty, even in the situation of a spatially static network of transmitters and receivers.

Multistatic passive coherent location resource optimization
SPIE Proceedings, 2017Passive Coherent Location (PCL) is a developing radar technique, in which the system processes reflections from opportunistic illumination sources in the environment for detection and tracking. Many developments and improvements of PCL implement pseudo-monostatic and bistatic radar configurations; however, with the proliferation of commercial ...

Passive Coherent Location as Cognitive Radar
2009 International Waveform Diversity and Design Conference, 2009Cognitive Radar describes a generic radar system that is capable of adapting its transmission waveforms and cooperation with other sensors in order to achieve superior detection, recognition, and tracking of targets. For example, the sensors of a cognitive radar system might use the illumination signals to carry broadcast data, allowing the sharing of ...
