The computational algorithm of determination of the bearing angle and distance to unobserved ground target are presented, the computational uncertainties are estimated. The triangular form of 3D detectors in one seismic location cell is offered. It allows minimizing distance and angle uncertainties in target direction. To improve the detection effectiveness, the optimal geometry disposition of 3D detectors in seismic location cells is determined. The offered method is effective in case of terrain relief where seismic-acoustic signal is propagated by approximately straight line. Therefore, this method can be applied only to homogenous medium, for example, to mountainous, solid rocky soil.

In the Military Doctrine of the Republic of Azerbaijan, one of the tasks of the Armed Forces and other armed formations only in peacetime is to ensure information security. However, it should be borne in mind that information security from the point of view of cybersecurity exists not only in peacetime, but also in all three security conditions defined in the Military Doctrine of Azerbaijan Republic, that is, “peacetime”, “real threat” and “war (armed conflict ) ". It can be concluded that in the Military Doctrine of the Republic of Azerbaijan there is a need to consider the adoption of the concepts of cyberspace and cybersecurity from the point of view of information security. There is no doubt that Armenia will not be able to restore its Armed Forces for a long time after the shameful defeat in the Second Karabakh War. However, Armenia will continue to strive for asymmetric warfare and may launch cyberattacks against Azerbaijan. The dynamic development of Azerbaijan in terms of technology and infrastructure creates favorable conditions for cyber attacks. Moreover, Azerbaijan may be subject to cyber attacks not only from the Republic of Armenia, but also in the interests of other state and non-governmental organizations.

Based on the research, it was established that the efficiency optical telecommunications systems substantially depends on the transmission characteristics fiber optic lines using WDM & DWDM (Wavelength Division Multiplexing & Dense WDM) technology. The FOCL consists of receiving and transmitting optical modules (ROM and TOM), and fiber optic cables (FOC). FOCL, due to the use spectral technologies and optical devices when transmitting optical signals, a powerful level in the communication channel (CC) and a small effective area of the FOC occur, which cause non-linear effects in the system.

Based on the study, it was established [1, 2] that the quality of functioning optical telecommunication systems significantly depends on fiber-optic transmission systems (FOTS), optical facilities and fiber-optic communication lines based on WDM/DWDM and HDWDM (Wavelength Division Multiplexing/ Dense WDM&High Dense WDM) technologies for transmission of any kind messages over almost any distance at the highest speeds. However, FOCL using spectral channel division systems for multiplexing optical fibers is one of the problems in the development next-generation multi-service networks NGN (Next Generation Network).
Thus, the study methods for improving the efficiency and noise immunity optical telecommunication networks using optical technology and the analysis of the information efficiency FOCL, which ensure the quality of service QoS (Quality of Service) for the transmission optical traffic, which is the most relevant.

vehicles (UAVs), as in all areas, has developed rapidly. Modern UAV systems require navigation systems that are resistant to all types of interferes. The application of modern radio-electronic warfare (REW) system against UAVs in the 44-day II Karabakh and Russian-Ukrainian wars had actualized for further improvement of navigation systems. Reliable navigation systems are needed to determine and track
the exact coordinates of targets in reconnaissance UAVs. Navigation systems must be sustainable and accurate for all stages of the flight. At the same time, they must be able to obtain the distance to the destination and exact coordinates of the the detected targets.

They enabled commanders to impact on the development of the battle scenarios by efficient maneuver and firepower in a short of period of time. Such situation lasted until the beginning of the XXI century in fact. However, the rapid development of technology opened the new era for anti-tank means. In order to fight effectively against tanks modern anti-tank missile “Javelin” and Israel made “Spike” can be shown an example of such weapon systems. For the first time “Javelin” was
used in the first and second Gulf Wars and evaluated positively. It was used in the fighting against tanks and armed vehicles of Iraqi Army and in the destruction of fire points and shelters strengthened by tandem warhead missiles.

The boost phase begins with the launch of the rocket and ends when propulsion engines push it off the Earth. The midcourse phase begins with the flight of the missile on a ballistic trajectory and continues until its warhead separates from the carrier and re-enters the atmosphere.
The terminal phase begins with the re-enter of its warhead the atmosphere and ends with its strike or explosion. The phases of ballistic missiles flight are taken into account when building ballistic missile defense systems. In addition to the three main phases of ballistic missiles discussed above, there is a concept of "post-boost phase" for ballistic missile defense systems

networks, as well as their telecommunications industry, are developing an
unprecedented change associated with the transition from the NGN concept to the future FN architectural concepts. This is a consequence of the rapid development optical, quantum and digital end-to-end technologies and a variety network applications. Therefore, one of the main requirements for fiber optic communication lines and optical networks is the ability to quickly increase the number communication channels and the bandwidth broadband multichannel systems in accordance with the growth in the amount of heterogeneous traffic transmitted.

navigation systems, which is the most important stage for all types of missions.
Despite its complexity, air navigation systems have been developed and brought to an autonomous mode today. With the help of both external navigation tools and onboard systems, it allows us to control any UAV with high accuracy at a distance of hundreds of kilometers.
When the pilot-operator prepares the UAV for flight, they first check that the elements of their navigation system are working and constantly monitor them through the monitor before and during the flight.
Navigation systems must be stable and accurate for all phases of flight. At the same time, they should also allow obtaining the distance to the destination and the exact coordinates of the current targets. As a result of research, the use of UAVs with stable navigation systems is more effective in recent wars. It also allows commanders to make the right decisions and keep the battlefield under stable surveillance, leading to the immediate destruction of important enemy targets. If UAVs transmit completely wrong coordinates during REW application, it leads to loss of control and
flying in different directions, and as a result of wrong planning, numerous personnel losses or defeat. Therefore, it is very important to carry out combat missions with UAVs that have stable navigation systems in all phases of war
