On an order of the maintenance firm Remote Sensing Laboratory Ltd. performed diagnostic investigations
in a flat after repair work. Our task was to sound an arch in the flat wall and to
establish position of reinforce elements in it. We received some microwave images of the object.
Figure shows the arch sketch and the images, which was received by RASCAN.
The images 1
were received on
internal side of the arch and the image 3
from the outside.
The results of the arch sounding
In this figure all dimensions is in mm. The image dimensions and positions correspond
to actual dimensions and positions of searching spot. We can see brickwork under
a layer of wall plaster in images 1 and 5. The radar shows the layers of bricks and
separate bricks with cement between them in this pictures. We can distinguish stretchers
and course of headers. They differ in dimensions and brightness.
The image 5 amalgamates two other images. We see that there isn't any seam between images.
One more detail is seen in images 2
. There are bright spots.
Two pointers mark them. We presume that there is one more profile.
It disposes perpendicularly to other profiles and has been welded to them.
As we know from building designer, there must be portal welded construction in arch
according to project on repair work. We searched flanker side of the arch also but we don't
see any uprise elements on RASCAN images. This is fault of the firm, which performed repair
works same month ago.
