Radio lighting based on ultrawideband dynamic chaos generators

Abstract

A problem of lighting objects and surfaces with artificial sources of noncoherent microwave radiation with the aim to observe them using radiometric equipment is considered. Transmitters based on dynamic chaos generators are used as sources of noncoherent wideband microwave radiation. An experimental sample of such a device, i.e., a radio lighting lamp based on a chaos microgenerator and its performance are presented.

On the Results in Physics Obtained in 2020‒2021

“…48 ) and some individual objects located in them were obtained. The possibility of detecting changes in these images related to the appearance of new objects was shown [ 74 – 81 ].…”

Image acquisition using artificial microwave radio lightning

“…In the articles [1][2][3], compact simple artificial sources of radiolight were introduced based on dynamic chaos in microwave range. They allow us to light up separated areas in space, but one still needs to have equipment that is capable of receiving such signals.…”

Experimental Model оf a Multibeam Device for Observation in Radio Light

“…The use of artificial radio illumination [5,6] is an alternative method, in which sources (radio light lamps) illuminate the entire observed area at once, while the surveillance systems are essentially passive and monitor the surrounding environment without emitting signals. This leads to two important consequences.…”

“…The developed prototype is designed for the frequency range of 3-5 GHz. Radio light lamps were used as radiation sources, in which the ultrawideband noiselike signal is a dynamic chaos in the microwave range [5,6]. The analog of the eye lens was implemented in the form of a radio lens.…”

“…Observation of objects in the surrounding space upon illumination by the radio light was carried out as follows. Two radio light lamps with a power of 2 mW each [5,6] were placed on one of the walls of the room in such a way that the room was uniformly illuminated but direct rays from the lamps did not fall into the receiving elements of the device. The observed object was located in front of the device at a distance of 1-3 m from it.…”
