Joint parameter estimation employing coherent passive MIMO radar
The Journal of Engineering, 2019 Passive multiple-input multiple-output radar is studied for the problem of joint estimation of target location and velocity. A general case is considered, where the signals of opportunity may be non-orthogonal and the clutter-plus-noise may be correlated.

Momentum and scalar transport within a vegetation canopy following atmospheric stability and seasonal canopy changes: the CHATS experiment [PDF]
Atmospheric Chemistry and Physics, 2012 Momentum and scalar (heat and water vapor) transfer between a walnut canopy and the overlying atmosphere are investigated for two seasonal periods (before and after leaf-out), and for five thermal stability regimes (free and forced convection, near ...

Ecosystem scale acoustic sensing reveals humpback whale behavior synchronous with herring spawning processes and re-evaluation finds no effect of sonar on humpback song occurrence in the Gulf of Maine in fall 2006. [PDF]
PLoS ONE, 2014 We show that humpback-whale vocalization behavior is synchronous with peak annual Atlantic herring spawning processes in the Gulf of Maine. With a passive, wide-aperture, densely-sampled, coherent hydrophone array towed north of Georges Bank in a Fall ...

Ambiguity function and Cramér-Rao bounds for universal mobile telecommunications system-based passive coherent location systems [PDF]
, 2012 The concerns are with the calculation of monostatic and bistatic ambiguity function (AF) of a quadrature phase shift keying (QPSK) signal where the pulses are shaped with a root raised cosine (RRC) filter. The monostatic and bistatic modified Cramér-Rao

GSM passive coherent location: Improving range resolution by mismatched filtering [PDF]
, 2022 6 S.The paper discusses the benefit of using mismatched filtering in GSM based passive radar systems. The Inverse Filter (IF) proposed here is derived and an implementation method is developed taking into account the GSM burst structure.

Passive Localization Through Channel Estimation of On-the-Air LTE Signals
IEEE Access, 2019 Wireless communication signal is a kind of coherent illuminator, and it can shed light on surrounding environments. The mobile terminal receives the signal and estimate the propagation channel, and can sense the moving objects passively. The localization

Multi-illuminator and multistatic passive radar [PDF]
, 2022 S.821-850Passive radar (PR) is always dependent on illuminators of opportunity and the waveform they provide. Using multiple different illumination sources as well as the distribution of multiple sensors in multistatic networks can provide some diversity.
