The determination and recognition of a poisson impulse radiation source activity standard

The radio impulse sequence receiving by the quadrature receiver in noises is considered in paper. It is supposed, that the received radio impulse number on the observation time interval is described by the Poisson distribution. The radio impulses random, independent elementary phases are distributed on the interval [0,2].

The radio impulse amplitude is contented regular and random components and distributed by Rice distribution. The joint probability density of going out receiver effect and received impulse number is found with the characteristic function method using.

The expressions for the Poisson source impulse radiation determination probability dependences as function of signal to noise ratio, the regular amplitude component to the square root of random amplitude component dispersion ratio and radiated impulse middle number are calculated. Furthermore the impulse radiation determination probability dependences were calculated for the condition, that the record impulses number was less 40 or bigger 40 and less 60 or bigger 60.

The determination probability reached maximum for the cluster, if the radiation impulse middle number appertained to that cluster. Therefore the record impulse number allows to estimate intensity of impulse source radiation.
