For these two targets, we only use the images from serial number SN_C21 for BMP2 and SN_132 for T72 at depression angle 17[degrees] as the training data.
Because the test target SAR images may be obtained from different depression angle, the adaption of a classification algorithm to depression angle is important for real application.
d] is the depression angle
to the horizon and [epsilon] is the angle from the horizon to the clutter patch.
In data fusion strategy, multiple images of a target in the same depression angle but in different aspects are selected.
In decision fusion strategy, multiple images of a target in the same depression angle but in different aspects are selected, which is the same as the first step in data fusion strategy.

AS A FUNCTION OF ALTITUDE
It can also introduce an automatic time delay in the release of retarded weapons, which may otherwise require an unacceptably large depression angle.
In this system the target is tracked automatically by TV contrast-lock or laser spot-tracking (giving a day/night capability), and slant range is computed continuously from the depression angle of the target and the rate of increase of this angle.
The baseline length of InSAR is 2 m; the vertical height of InSAR master channel is 8 km; the depression angle and the incline angle of InSAR baseline are 30 deg and 60 deg, respectively.
Scenarios II to IV share the same set of parameters with scenario I except that the baseline length in scenario II is 6 m; the incline angle of InSAR baseline in scenario III is 45 deg; the depression angle and the incline angle of the baseline in scenario IV are 60 deg and 30 deg, respectively.
and the slant depression angle can be calculated by
2, if the depression angle [theta] changes, then 2D image coordinates ([x.
