The effectiveness of the radio monitoring system depends on the correctness of determining the coordinates of the location of radio monitoring tools at the stage of planning their application. The decision on the choice of position for radio monitoring should consider the heterogeneity of the terrain in the area of tasks, the presence of natural and electronic interference, which can lead to deterioration of conditions for receiving signals from radio sources. The use of the known methods, techniques, and algorithms for the placement of radio monitoring tools does not fully consider the requirements mentioned above. This leads to a decrease in the effectiveness of radio monitoring in a particular area of performance. Therefore, the purpose of this article is to develop a methodology for spatial placement of radio monitoring to ensure the effectiveness of radio monitoring in a particular area of tasks, taking into account the heterogeneity of the terrain, as well as natural and artificial electronic interference. Determining the coordinates of radio monitoring facilities included in the radio monitoring system involves determining the allowable options for their placement in a particular area of tasks using the mathematical apparatus of the dense placement function and its hodograph and further thinning of the matrix of acceptable solutions based on restrictions. A distinctive feature of the proposed approach is the optimization problem of geometric design for radio monitoring of complex spatial forms. At the same time, the peculiarities of completing the radio monitoring system using different types are also taken into account. It is expedient to use the developed technique for the planning of application of the system of radio monitoring; formation of working decisions on the construction of the radio monitoring system; assessing the quality of decisions and the formation of alternatives; ensuring the adaptation of the structure of the radio monitoring system to changes in the situation under the influence of the enemy and the formation of new zones of electronic interference.

Currently, radio monitoring systems are being actively improved in the direction of expanding the range of operating frequencies and the width of the spectrum of processed signals, which in some cases requires changing approaches to the design of their receiving devices. The purpose of the article is to substantiate the methods and circuit design options for implementing a receiver of an ultra-wide-range radio monitoring system and to justify the sequence of selecting the element base and calculating the parameters of the receiving path. The research proves expedient to choose the infradine structure of the radio receiving path as a basis, in which the frequency of the mirror channel is located far from the frequency of the main channel, so the mirror channel is easily suppressed by a simple low-pass filter. One of the main problems that arise when designing ultra-wideband radio receivers is the simultaneous provision of a large dynamic range and a low noise figure. To reduce the noise figure, a variant of constructing a path was proposed, starting with a low-noise amplifier with increased parameters of nonlinear selectivity, which is acceptable if there is a low probability of intermodulation combinations. The article suggests a receiver with an operating frequency range of 0.5–18 GHz and an analogto-digital converter with a speed of up to 10.4 GSPS. The element base was selected for the receiving devices and the main parameters of the path were calculated. A number of examples are used to analyze the ways to increase the dynamic range of a radio receiver and the influence of element base parameters on the device performance. The main technical characteristics of the radio receiver for effective operation of modern radio monitoring systems and the ways to increase the dynamic range thereof are described.
