ALGORITHM OF DETECTION SPATIO-TEMPORAL NOISE-LIKE SIGNAL WITH THE UNKNOWN PARAMETERS WITH MANY-CHANNEL RECEPTION

Александр Дмитриевич Абрамов, Антон Дмитриевич Собколов

Abstract


Considered characteristic task for radio astronomy, detection spatio-temporal noise-like signal emitted by extended radiation source, observations of which are conducted in a parametrically uncertain noise conditions. The methodology of its solution is given, the main basis of which is the likelihood ratio criterion. Based on the developed methodology for multichannel reception, a detection technology was synthesized, which, unlike known ones, does not require knowledge of the interference power for forming a threshold level. The technology uses well-designed computational operations and tabulated statistics, it allows to control the magnitude of the error probability of the first kind

Keywords


hypothesis testing; noise-like signal; likelihood ratio criterion; planar multi-channel reception
