Simulated & theoretical SNR in passive bistatic noise radar processing [PDF]
2016 IEEE Radar Conference (RadarConf), 2016 The theoretical output signal-to-noise ratio (SNR) values computed for cross-correlation, least-squares (LS) and various versions of the least mean square (LMS) algorithm have been found to agree with the respective output SNRs exhibited by range profile estimates generated by these algorithms in Matlab when the transmitted noise waveform's spectrum is

Electronics Letters, Volume 62, Issue 1, January/December 2026.This letter presents an over‐the‐air ISAC study in the 5G‐NR FR1 band using an SNR‐based beam‐sweeping sensing approach. In the SIMO scenario, multiple distributed receive nodes are combined with beam sweeping to enable angle estimation under narrowband sub‐6 GHz conditions.

A Range-Doppler-Angle Estimation Method for Passive Bistatic Radar
CoRR, 2017 In this paper, an effective target detection and localization method is proposed for a passive bistatic radar (PBR) system. The PBR system consists of a commercial FM radio station, which is a non-cooperative illuminator of opportunity (IO), referred to as the transmitter antenna and multiple surveillance antennas that form an antenna array, e.g ...

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.The study presents the design and development of a plasma‐based antenna array system for the UHF band. The system features an omnidirectional plasma antenna as its active radiator, a novel approach that has not been previously explored. Surrounding plasma reflectors form a reconfigurable array around the monopole plasma antenna for beam shaping and ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This work proposes a micro‐Doppler‐assisted particle‐filtering track‐before‐detect (mD‐PF‐TBD) algorithm with a variable‐particle mechanism to robustly track UAVs in passive radar systems, particularly when they enter the Doppler‐blind zone (DBZ). As the target Doppler frequency approaches zero, the algorithm adaptively reallocates particles towards ...

On the effects of clock offset in OFDM-based Passive Bistatic Radar
2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013 In Passive Bistatic Radar (PBR) a local communications transmitter is used as an illuminator. A Line Of Sight (LOS) signal is captured to use as a template for radar processing. This may be cleaned via demodulation and remodulation, removing short-delay copies and sensor noise. However differences between the transmitter clock and local clock cause the

Range‐Free Localisation for Monostatic Passive Radar Employing Multi‐Narrowband Illuminators
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Range‐free localisation is considered for monostatic passive radar with multiple narrowband illuminators under unreliable time‐delay (range) measurements. Doppler/DOA (and optional Doppler‐rate) are fused in an ML framework, where velocity is iteratively updated to reduce the original 6‐D optimisation to a 3‐D position search.

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.We propose a multidomain joint orthogonal subspace projection algorithm based on angle‐based high‐order singular value decomposition (HOSVD). By constructing a three‐dimensional range‐Doppler‐angle tensor from multidirectional beamformed data, the method exploits the distinct spatial directivity and strong range correlation of the RFI to jointly ...

Passive bistatic noise radar using DVB-T signals
IET Radar, Sonar & Navigation, 2010 This study presents a new approach to passively detect targets using noise-like emitters of opportunity. This method combines the Wiener filtering to achieve clutter rejection and a proposed adaptation to noise-like signals of the amplitude and phase estimation (APES) method.
