Abstract:
Article is devoted a conclusion of analytical expressions for probability of a false alarm and the signal admission at maximally probable detection and direction finding several frequency-inseparable flat radio-waves. It is shown that the decision statistics of detection are representable as the form of the sum of the square-law forms constructed on measured complex ranges of stress on yields of elements of antenna system. The template of the square-law form is projective. With use of the device of one-dimensional characteristic functions it is shown that the solving statistics has a hi-square allocation with number of the degrees of freedom, equal to product of number of found radio-waves on number of measurements. Exact analytical expressions for probability of a false alarm and the skip of signal are received. It is shown that the yielded probabilities are expressed through incomplete normalized gamma function. Article contains 9 bibliographic sources of the information.
