Заголовок статьи: Models of signals and interference when detecting targets in a spatially distributed information system of radar modules

Резюме

Models of signals and interference in a spatially distributed information system of radio engineering monitoring (PRISRM) are substantiated. The set of echo signals received by several PRISRM positions when the target is irradiated with one transmitting position is considered in order to solve the problem of detecting an air target. The structure of signal processing algorithms at reception positions with a phased array antenna (PAA) is determined. In this case, the partial interposition decorrelation of interference, noise and a high degree of interference correlation over the PAA aperture are taken into account. The scheme of a target detector built in accordance with this algorithm is proposed. The efficiency of the considered processing algorithms is estimated regarding various consideration degrees of interposition interference decorrelation.
