Abstract:
On the basis of the theory of an optimum filtration of casual sequences changing the properties during the casual moments of time the recurrent algorithm of an estimating and identification of parametres of a pulse signal with precisely known duration, observed against a pulse hindrance of greater duration is developed. Features of algorithm, is aprioristic data on duration of an impulse radiated or reflected from the purpose (a typical case for the homing radar-tracking system). It leads to complication of algorithm of a filtration in comparison with the available algorithms of processing synthesised in the assumption, that duration of an impulse is casual. The additional aprioristic information having determined character, in structure of casual entrance is discrete-continuous sequence, leads to a strongly pronounced aftereffect. In the filtration theory aftereffect presence is provided - for the process description in the Markovsky kind the increase in quantity of conditions and the phase co-ordinates describing process is offered. It does processing enough difficult. In article more simple algorithm of a filtration is developed. Algorithm simplification is reached at the expense of use of available laws and the repetitions caused by presence at casual process of determined transitions. By the estimations received by means of developed algorithm the operating signal of the radar-tracking system of angular support of the purpose which is observed against a clutter signal radiated with other direction is calculated.
