The hierarchical structure of ARM equipment, its composition, functions, and the
main technical specifications for solving ARM problems in industrial centers and
in open terrain, to reveal CEE in the monitored regions and its boundaries, and to
check the measure’s effectiveness to prevent information leakage, is well described
in Chapter 2. The solution to all these problems in corpore is related to certain finan-
cial difficulties. The way to solve this situation is to use multifunctional equipment
to execute the greatest number of ARM tasks with the highest effectiveness and at
the least expense. In the present chapter, we consider how to execute ARM tasks on
the basis of one piece of equipment only, namely, the multi-channel (in the minimal
configuration of double-channel) digital receiver.
The detection of radio signals with the dynamic frequency-time structure is one
of the additional possibilities of this equipment. The high rate of panoramic anal-
ysis ensures the possibility to reliably reveal these signals. Figure 5.1 shows the
panoramic spectrum analysis results with the extreme value accumulation in 1, 20,
and 50 s after detection begins, when observing the real POFT communication line.
In this case, the spectral analysis mode with the rate of 140MHz/s is used. The pre-
sented result analysis shows that, 30–50 s after POFT signal detection, the equip-
ment allows the determination of most frequency positions.
One of the most important parameters of the technical means for the search and
detection of new RES, i.e., defining the radius of the RM post’s action zone, is the
real sensitivity of the panoramic analysis equipment.
