This paper presents the first successful drone detection results using a 5G network as a
source of illumination in a passive radar system. Furthermore, a novel adaptive strategy for …

Monitoring the Earth's surface from the low Earth orbit (LEO) by synthetic aperture radar
(SAR) provides meaningful information about a number of human activities such as the …

Range Doppler coupling is a range bias resulting from the use of linear frequency
modulated waveforms. This coupling impacts radar returns of highly accelerating targets …

High frequency radar observations of satellites are altered by the impacts of range Doppler
coupling along with ambiguous Doppler measurements, making the estimation of true range …

The paper presents the concept and its empirical validation of the use of passive bistatic
radar based on the LOFAR radio telescope and commercial digital radio DAB+ illuminator …

There is increasing interest in space domain awareness worldwide, motivating investigation
of the use of non-traditional sensors for space surveillance. One such class of sensor is VHF …

The paper presents the idea and results of the experimental trials devoted to passive
multistatic observation of space objects in low-Earth orbits employing an astronomical …

Several pioneering works have presented experimental results of 5G-based passive radars.
In those works, the illumination source is a signal transmitted by the 5G base station …

The paper presents the concept and results of experiments devoted to verifying empirically
the potential capability of long-distance space object observation by radar system employing …

In this paper we provide an overview of the passive radar concept before covering
capabilities and opportunities for low Earth orbit (LEO) Space Situational Awareness (SSA) …
