“…This allows, when calculating the characteristics of a laser alarm system, to make the transition from uniform reflection, which is described by Lambert's law, to a substantially non-uniform distribution, which is characteristic of laser radiation reflection on diffraction gratings [15,16]. The use of diffractively reflecting coatings as part of a laser signaling system makes it possible to provide [1,[17][18][19][20][21]: multiple increase in the power of the reflected laser radiation; the possibility of forming a certain number of "laser barriers" along the diffraction maxima propagation directions of the scattering diagram of the diffractively reflected coating.…”

The paper substantiates the prospects of using diffraction-reflecting coatings as part of laser signaling systems to improve reliability. An increase in the such alarm systems reliability occurs due to a power increase of reflected laser radiation and the possibility of forming a certain number of "laser barriers" in different directions. In general, laser signaling systems with diffractively reflecting coatings, in contrast to existing laser signaling systems, allow solving additional tasks of assessing the movement speed of objects in the protected area and determining their movement directions.

“…The multichannel information-measuring systems for controlling aircraft MP, which operate in the radio-technical wave range, have been sufficiently studied [3][4][5][6][7][13][14][15]. The problems of combining (and separating) channels in such systems are solved for mobile radio lines mainly by the frequency method of channel separation [3,10,11], and for cable lines using digital time-division multiplexing methods [14].…”

Improving the accuracy of measuring motion parameters and the volume of information exchange with aircraft requires the modern development of multifunctional radio systems that allow the combination of information and measuring channels due to frequency (time) signal selection. However, radio systems have limitations on the number and accuracy of the measurement of aircraft motion parameters, as well as information transfer rates. These restrictions will make it possible to remove laser systems for measuring with high accuracy the parameters of motion of aircraft. Similar laser systems are widely used in transmitting information to stationary or quasi-stationary objects. As a result, there was a need to overcome the contradiction between the requirements for the technical characteristics of radio systems and the capabilities of the existing scientific and methodological apparatus for synthesizing the signals of laser information-measuring systems for monitoring the parameters of aircraft motion. The theoretical foundations of the formation and selection of laser signals for combining the information and measuring channels of laser information-measuring systems are proposed and investigated. A comparison is made with known methods of combining (combining) the information and measuring channels of radio engineering systems and the features of using a spectrum of laser radiation formed by pairs of longitudinal modes that “color” each channel signal for their selection at reception. When receiving optical pairs of longitudinal modes, the intermode beat frequencies turn into radio engineering subcarriers that are well filtered and selectable. Based on the results of mathematical modeling and combinations of longitudinal modes, the choice of elements of a modified selector of longitudinal modes of laser information-measuring systems is substantiated. This determines the importance and usefulness of work for applied systems for measuring the parameters of movement of aircraft.
