Assessment of the influence of the manufacturing quality of a reflective coating on the angular distribution function of the reflected radiation intensity of laser signaling systems

Abstract

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.

Measurement Errors Affecting the Characteristics of Multi-Position Systems, and Ways to Reduce Them

“…It is believed that the curvature of the earth's surface and the refraction of radio waves are taken into account. Then, in a single rectangular coordinate system, the estimates of the rectangular coordinates of the air object associated with the estimates of the spherical coordinates relative to the radar station of the system by functional dependence: Errors in accounting for the curvature of the Earth's surface at the present time can be significantly reduced by taking into account the information of digital maps of the area, remote sensing of the Earth, modern methods of surface control [14][15].…”
