Abstract
The mathematical formulation of the problem of determining the coordinates of targets in the network of counter-battery radars is formulated. It has been established that the problem of estimating the coordinates of targets in the network of counter-battery radars for an excessive number of estimates of primary coordinates should be considered as a statistical problem. The method for determining the coordinates of the firing positions of roving mortars has been improved, in which, in contrast to the known ones, the coordinates of targets on the flight trajectory are coordinated with space and time and the information is processed by a network of counter-battery radars. The developed simulation mathematical model for determining the coordinates of the firing positions of roving mortars by a network of counter-battery radars. Simulation modeling of the method for determining the coordinates of the firing positions of roving mortars by a network of counter-battery radars has been carried out. It has been established that the use of a network of radars makes it possible to increase the accuracy of determining the coordinates of the firing means on average from 23 % to 71 %, depending on the number of counter-battery radars in the network. It has also been found that the appropriate number of counter-battery warfare radars in the network is three or four. A further increase in the number of counter-battery warfare radars in the network does not lead to a significant increase in the accuracy of determining the coordinates of artillery and mortar firing positions. In carrying out further research, it is necessary to develop a method for the spatial separation of elements of a group of targets and interfering objects by a network of counter-battery warfare radars

A further increase in the number of counter-battery activities (CBA) radars in the network does not lead to a significant increase in the accuracy of determining the coordinates of the firing position
The method for determining the coordinates of roving firing positions has been improved, in which, unlike the known ones, the coordinates of targets on the flight path are measured consistent with space and time and the information is processed by the CBA radars network (Fig. 1)
Summary
The most common types of terrorist attacks are grenade launcher attacks and mortar attacks. The use of roving mortars by terrorists is due to the following: – firstly, mortars are quite easy to make in a handicraft way from scrap materials; – secondly, terrorists often locate mortar firing positions in residential areas, refugee camps, near schools, hospitals, hiding behind a «human shield»; – thirdly, regular shelling from mortars has a fairly strong psychological impact. The experience of conducting counter-battery activities (CBA) showed a number of problems in countering roving mortars. One of the main problems is significant errors in determining the position of the mine and, the coordinates of the firing positions of roving mortars to deliver an adequate retaliatory strike in order to destroy the firing weapon. Improving the accuracy of determining the coordinates of the firing positions of roving mortars is especially important when firing from residential areas, school grounds, kindergartens, etc
