Query: Singular FIOs in SAR Imaging, II: Transmitter and Receiver at Different
  Speeds   In this article, we consider two bistatic cases arising in synthetic aperture
radar imaging: when the transmitter and receiver are both moving with different
speeds along a single line parallel to the ground in the same direction or in
the opposite directions. In both cases, we classify the forward operator $\Fc$
as a Fourier integral operator with fold/blowdown singularities. Next we
analyze the normal operator $\Fc^*\Fc$ in both cases (where $\Fc^{*}$ is the
$L^{2}$-adjoint of $\Fc$). When the transmitter and receiver move in the same
direction, we prove that $\Fc^*\Fc$ belongs to a class of operators associated
to two cleanly intersecting Lagrangians, $I^{p,l} (\Delta, C_1)$. When they
move in opposite directions, $\Fc^*\Fc$ is a sum of such operators. In both
cases artifacts appear and we show that they are, in general, as strong as the
bona-fide part of the image. Moreover, we demonstrate that as soon as the
source and receiver start to move in opposite directions, there is an
interesting bifurcation in the type of artifact that appears in the image.
