Active-Passive Radar for Radar Imaging from Aerospace Carriers
IEEE EUROCON 2021 - 19th International Conference on Smart Technologies, 2021Algorithms for radar imaging of the underlying surface from aerospace carriers have been synthesized. In doing so, we have considered two possible ways of image reception based on methods of active and passive remote sensing. On this basis, a radar complex, which allows forming images proportional to either the specific effective surface scattering or ...

Abstract Passive bistatic radar (PBR) is the name given to a bistatic radar that makes use of emissions from broadcast, communications or radionavigation transmitters rather than a dedicated, co-operative radar transmitter. Such systems have a number of potential advantages. The receiver is passive and so potentially undetectable.

Feasibility of UMTS signal for passive radar
2017 25th Signal Processing and Communications Applications Conference (SIU), 2017Passive radar systems are non-cooperative systems that can detect targets using illuminators already in place. Detection and tracking are carried out with lower costs, difficulty of jamming and including no need for frequency allocation by utilizing different types of waveforms such as television, radio, mobile communication signals.

Passive bistatic radar (PBR) demonstrator
IET International Conference on Radar Systems 2007, 2007We present a system characterisation of a passive bistatic radar (PBR). The system under investigation exploits 'illuminators of opportunity', which in this case are commercial, non-cooperative, VHF FM broadcast transmissions. The paper demonstrates the detection of large passenger-jet aircraft over central London.

Fidelity and Complexity in Passive Radar Simulations
2015 IEEE 16th International Symposium on High Assurance Systems Engineering, 2015A case study of the trade off between fidelity and complexity is presented for a passive radar simulator. Although it is possible to accurately model the underlying physics, signal processing, and environment of a radar, the resulting model might be both too complex and too costly to evaluate. Instead, simplifications of various model attributes reduce

Noncooperative registration for multistatic passive radars
IEEE Transactions on Aerospace and Electronic Systems, 2016Multistatic passive radars localize targets by using multiple bistatic range measurements. Multistatic localization requires all range measurements to be unbiased. It is proved by real data processing that registration is an important topic to be addressed. Traditionally, atomic clocks or GPS are used to achieve unbiased measurements.

Automatic Target Recognition for Passive Radar
IEEE Transactions on Aerospace and Electronic Systems, 2014Air-traffic controllers cannot identify air vehicles flying with a defective or nonexistent transponder. Primary radar does not help, because it cannot classify air vehicles from echoes. Passive radar offers a potential solution, the main difficulty lying in the analysis of the data.

Passive radar via LTE signals of opportunity
2014 IEEE International Conference on Communications Workshops (ICC), 2014Passive radars relying on signals of opportunity enable new applications based on stealth tracking of targets without the need of radar signals emissions. Long term evolution (LTE) base stations employing orthogonal frequency division multiplexing (OFDM) signals are excellent candidates as illuminators of opportunity thanks to their wide availability ...
