Multistatic Localisation in Passive Radar System for LEO Space Objects Observation Using Terrestrial Illuminators and LOFAR Radio Telescope

open access: yesIET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
The paper unveils groundbreaking research on the passive multistatic radar localisation of low‐Earth orbit (LEO) space objects using terrestrial digital radio transmitters operating in the VHF band that served as illuminators of opportunity and a LOFAR radio telescope employed as a surveillance receiver.

Using Particle Filter for Estimating Velocity of Maneuvering Target Being Tracked by Passive Radar

open access: yesSyrian Journal for Science and Innovation
Tracking a target is achieved by estimating its range and velocity, and this process has two types: Bistatic Tracking and Cartesian Tracking. In a passive radar system, the bistatic tracking is achieved by processing the bistatic geometry “One non ...

Entanglement-Assisted Joint Monostatic-Bistatic Radars

open access: yesEntropy, 2022
With the help of entanglement, we can build quantum sensors with sensitivity better than that of classical sensors. In this paper we propose an entanglement assisted (EA) joint monostatic-bistatic quantum radar scheme, which significantly outperforms corresponding conventional radars.

Joint DOD and DOA Estimation in Bistatic MIMO Radar With Distributed Nested Arrays

open access: yesIEEE Access, 2019
In this paper, we investigate the problem of joint direction of departure (DOD) and the direction of arrival (DOA) estimation in bistatic MIMO radar. A new bistatic MIMO radar with the distributed nested array is proposed. Based on the new array, the DOD

Investigating SAR algorithm for spaceborne interferometric oil spill detection [PDF]

open access: yes, 2016
The environmental damages and recovery of terrestrial ecosystems from oil spills can last decades. Oil spills have been responsible for loss of aquamarine lives, organisms, trees, vegetation, birds and wildlife. Although there are several methods through

Bistatic laptop radar: an affordable, silent radar alternative [PDF]

open access: yesProceedings of the 1996 IEEE National Radar Conference, 2002
Passive sensor technology based on noncooperative, coherent broadband sensing can provide a lower power consumption, low cost, light weight and compact (man portable) alternative to active radar sensors in support of quiet surveillance and radio frequency (RF) target imaging.

Spectral Properties of Bistatic Radar Signals Using the Ray Tracing Technique and a Facet Approach

open access: yesAerospace
Bistatic radar experiments have been used to study surface characteristics of extra-terrestrial bodies in the Solar System, including the Moon, Venus, Mars, and Titan. This paper proposes a 3D model to characterize the scattered field of a gaussian rough
