Second-order variation of an integral
I was reading the paper SISAR Imaging for Space Debris based on Nanosatellites, in which the Fresnel-Kirchoff diffraction formula is applied for a scenario in which the receiver, transmitter and ...

How can the Fourier delta function produce different matrices in single-pixel imaging?
The pattern in the masks used for single-pixel imaging are created applying equation $(1)$,
$$P_\phi (x,y) = \frac{1}{2} \left[ 1 +| F^{-1} \{\delta_H (u,v) e^{i\phi}\}|\right], \tag{1}$$
in which the ...

Why does CW imaging not provide the same data as Pulsed imaging?
"Unlike pulsed THz imaging, the CW imaging (...) only yields intensity data and does not provide any depth, frequency-domain or time-domain information (...)." [1]
Why does a pulsed signal ...

Implement EPR Imaging deconvolution
I have bruker's EPRI data and I want to deconvolute it.
I read some article, that says
$$
f(r) = x(r) \circledast g(r) \\
F(ω) = X(ω) \times G(ω) \\
X(ω) = \frac{F(ω)}{G(ω)}
$$
$f(r)$: imaging spectre,...

3D Surface Related Multiple Elmination (SRME)
Let's assume we are looking at first order multiples of the same surface (i.e no peg leg, etc). I am looking at marine 3D SRME and I am a little confused as to how this works. I understand that in the ...
