Server cabinet and data centre based on server cabinet

FIELD: information technology.

SUBSTANCE: server cabinet comprises at least two functional units, a plurality of intra-server antennas and a plurality of inter-server antennas. The functional units are located in a vertical direction with the formation of a server core; the intra-server antennas are located in the vertical direction, located at the side of the server core, and are electrically connected to the corresponding functional units, and the adjacent intra-server antennas are connected in a wireless manner. When transmitting a radio signal within the server cabinet, the intra-server antennas located in the vertical direction form a transmission path. Because the intra-server antennas are located at the side of the server core, the electromagnetic radiation generated by the radio signal during transmission process has a relatively small impact on the functional units.

EFFECT: reducing impact of the electromagnetic radiation on various electronic devices and equipment, which increases the service life of electronic devices and equipment and improves the quality of the radio signal transmission.

SUBSTANCE: invention relates to radio equipment and can be used at design and operation of radio direction finding complexes or radio communication systems of portable, mobile (onboard) and stationary location. On every element of an antenna array, an interval is recorded on time interval [0,T], formation of discrete spectrum of field intensity is performed using a Fourier transformation procedure; with that, for each of the obtained spectrum components there found is a vector of complex amplitudes/auxiliary sources as an approximate solution of a matrix-vector equation using a quasisolution procedure. Number of auxiliary sources is determined as number of the most significant proper numbers of an autocorrelation matrix of signals received by the antenna array, i.e. maximum and differing from the rest ones as to the value at least by one order. Then, values of a spectral component field are determined at an arbitrary point of antenna array plane (a virtual signal receiving channel is formed) as a scalar product of the determined vector of complex amplitudes of auxiliary sources and the corresponding vector of the virtual signal receiving channel.

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.

SUBSTANCE: invention relates to search devices and is designed for detecting objects based on reception of signals resulting from secondary re-radiation with change in the spectrum of the probing signal. The detector has first and second generators which emit probing signals at close frequencies f1 and f2, and a receiver with a receiving antenna which receives signals in a frequency range close to the frequencies f1 and f2.

In another mode, the decision is made if the receiver detects a signal at frequency f1, which is modulated with frequency F, wherein the probing signal at frequency f2 is modulated with frequency F.
