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

Multistatic passive coherent location using multilateration techniques
SPIE Proceedings, 2016Passive Coherent Location (PCL) is a developing radar field, 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 communication

Passive tracking with sensors of opportunity using passive coherent location
SPIE Proceedings, 2008Passive coherent location (PCL), which uses the commercial signals as illuminators of opportunity, is an emerging technology in air defense systems. The advantages of PCL are low cost, low vulnerability to electronic counter measures, early detection of stealthy targets and low-altitude detection.

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 ...

A multistatic passive coherent location system with receiver location constraints
2017 18th International Radar Symposium (IRS), 2017A multistatic passive coherent location system has been designed during an eight month lasting trial starting in the end of 2015. The demonstration system exploits the regional single-frequency network (SFN) of DVB-T transmissions from two transmit stations in the area of Munich, Germany.

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.

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 radar Doppler estimation for passive coherent location
2017 IEEE Radar Conference (RadarConf), 2017The availability of multiple transmitters in a passive coherent location (PCL) scenario allow for multistatic velocity estimation. This paper develops the mathematical framework and methods to estimate the velocity vector for a target in motion for a passive coherent location system.

Robust Passive Coherent Location via Nonlinearly Constrained Least Squares
2021 IEEE 12th Latin America Symposium on Circuits and System (LASCAS), 2021This paper addresses the problem of target location by means of a passive radar. Existing approaches based on time-difference-of-arrival (TDOA) measurements, namely spherical interpolation and spherical intersection, are revisited for the case of single transmitter and multiple receivers.

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.
