Decentralized searching of multiple unknown and transient radio sources

2013 IEEE International Conference on Robotics and Automation, 2013
We develop a decentralized algorithm to coordinate a group of mobile robots to search for unknown and transient radio sources. In addition to limited mobility and ranges of communication and sensing, the robot team has to deal with challenges from signal source anonymity, short transmission duration, and variable transmission power.

Monte Carlo simultaneous localization of multiple unknown transient radio sources using a mobile robot with a directional antenna

2009 IEEE International Conference on Robotics and Automation, 2009
We report our system and algorithm developments that enable a single mobile robot equipped with a directional antenna to simultaneously localize multiple unknown transient radio sources. Due to signal source anonymity, short transmission durations, and dynamic transmission patterns, the robot cannot treat the radio sources as continuous radio beacons ...

A group sparsity imaging algorithm for transient radio sources

Astronomy and Computing, 2013
Abstract Radio interferometers can achieve high spatial resolution for temporally constant sources by combining data observed over long periods of time. Recent imaging algorithms reconstruct smoothly varying sources by representing temporal variation in polynomial or Fourier bases.

Transient radio source near the galactic centre

Nature, 1976
A VARIETY of interesting objects have been discovered in recent years within several arc min of the galactic centre. These include the main (east and west)1 components of the radio source Sgr A, a compact radio source2 at the centre of Sgr A West which may be the galactic nucleus, and a group of infrared sources3 in a region of ∼ 20″ diameter ...

A Transient Radio Source near the Center of the Milky Way Galaxy

Science, 1992
In late December 1990, a new radio source appeared near the center of our galaxy rivaling the intensity of Sgr A * (the compact radio source at the galactic center). Following its first detection, the flux density of the galactic center transient (GCT) increased rapidly to a maximum 1 month later, and then declined ...

Transient nature of radio source NVSS J1957+35

Advances in Space Research, 2019
Abstract We have searched for transient and variable radio sources in the field of Galactic micro-quasar Cygnus X-1 near 1.4 GHz (L band) using data from the Karl G. Jansky Very Large Array. We used twenty years of data between 1983 and 2003. We found a source NVSS J1957+35 showing transient behavior. The source was also mentioned earlier in NVSS and

Search for radio transients and recent detection of radio sources in the RATAN-600 surveys of 1980–1994

Astrophysical Bulletin, 2016
In the paper we present the results of search for transient sources using the data from the surveys conducted onRATAN-600 at 7.6 cmin the time period of 1980–1994.We detected three events at a level of 3–5σ. A search for coincidenceswith detected transient events was carried out. Using the data from radio and optical surveys and the VizieR, SIMBAD, and
