Modeling and Compensating Temperature-Dependent Non-Uniformity Noise in IR Microbolometer Cameras
(2016)
Images rendered by uncooled microbolometer-based infrared (IR) cameras are severely degraded by the spatial non-uniformity (NU) noise. The NU noise imposes a fixed-pattern over the true images, and the intensity of the ...
Fiber-based Infrared Heterodyne Technology for the PFI: On the possibility of breaking the noise temperature quantum limit with cross-correlation
(2018)
We present concept and first experimental lab results for a novel heterodyne correlation receiver architecture and demonstrate that it can surpass the standard quantum limit (SQL) for the noise temperature by "correlating ...
On the Possibility of Breaking the Heterodyne Detection Quantum Noise Limit With Cross-Correlation
(2018)
The cross-correlation sensitivity of two identical balanced photodiode heterodyne receivers is characterized. Both the balanced photodiodes receive the same weak signal split up equally, a situation equivalent to an ...
Modeling the Impact of 5G Leakage on Weather Prediction
(ArXiv e-prints, 2020)
The 5G band allocated in the 26 GHz spectrum referred to as 3GPP band n258, has generated a lot of anxiety and concern in the meteorological data forecasting community including the National Oceanic and Atmospheric ...
Dynamics of a planar Coulomb Gas
(2018)
We study the long-time behavior of the dynamics of interacting planar Brownian particles, confined by an external field and subject to a singular pair repulsion. The invariant law is an exchangeable Boltzmann-Gibbs measure. ...
The Atacama Cosmology Telescope: Calibration with the Wilkinson Microwave Anisotropy Probe Using Cross-correlations
(2011)
We present a new calibration method based on cross-correlations with WMAP and apply it to data from the Atacama Cosmology Telescope (ACT). ACT's observing strategy and map making procedure allows an unbiased reconstruction ...
