6. SENSOR CONSTRUCTION
The sensor consists of separate units (Rx, Tx) placed in dust- and splash-proof
enclosures.
6.1.
Rx construction
6.1.1.
Rx construction and its fastening elements to the support are shown in fig. 6.1. The
bearing structure of Rx 1is a parabolic antenna. The exciter is fixed inside of this
antenna (in the focus of parabola). The detection camera with the cover is installed
on this exciter. The processing module is fixed on the sidewall inside the antenna.
Rx connection to the JB or SU is realized with the cable 12 stretched through the
cable entry. Rx is fixed on the support with the bracket 7 and buckles 4. At first the
bracket is fixed on the support, and then Rx is fixed to the bracket with the nut 8.
The opening of the cover
14 provides the access to the control, adjustment and
indication elements. The arrangement and marking of the elements under the
cover
14 are shown in fig. 6.2.
The main operating position of Rx is shown in fig.6.1 (to the left of the support, if
one looks from the emission side). In the cases when it is impossible to fix Rx on
the left of the support, it can be fixed on the right of the support.
In this case the
plugs 3 should be installed in two holes in the upper part of the antenna, and
two holes of the antennas should be opened in the lower part.
It is necessary to
prevent the condensate inside the antennas.

Tx Construction
6.2.1.
Tx construction is generally the same as Rx construction (see fig.6.1). There are
the following differences: the microwave generator is fixed on the exciter instead
of the detection camera and it is connected to the modulator; cover 14, control,
adjustment and indication elements are absent.
