MULTI-STATION PASSIVE LOCATION RADIO SYSTEM (INDUSTRIAL VISION)

摘要

FIELD: radio engineering, communication.;SUBSTANCE: multi-station passive location radio system (MRS PL) consists of a structured antenna array and a high-performance computer. The structure of the array is similar to that of the retina. The array consists of active cells which are grouped into separate antenna fields, signals from which are transmitted to controllers of a second and, further grouped likewise, to the next layers until the input of the computer. The controllers and the computer employ a spatial selection algorithm. The technical result of the operation of the MRS PL is provided by the dimensions of the separate antenna fields, which must be much larger than the operating wavelength, used to achieve the required sensitivity of the noise attenuation principle by selecting the number of array cells. To reduce the amount of computations when scanning, the computer employs a sector detection algorithm, which is the spatial selection algorithm with another input parameter.;EFFECT: high noise-immunity and accuracy of detecting received signals.;10 cl, 3 dwg
