Calculation-analytical model of radar station accuracy characteristics under stochastic changes of amplitude and phase

The impact of destructive factors both on the amplitude-phase-frequency response (APFR) of the transmitting path and on the amplitude-phase distribution (APD) at the antenna opening of the space monitoring radar station (SMR) significantly reduces its accuracy characteristics. The existing models of accuracy characteristics do not fully allow to take into account the destructive influence of stochastic changes in amplitude and phase, which does not allow to develop an adaptive algorithm for prompt and accurate compensation of de- destructive factors. To solve the problem, it is necessary to formalise the computational-analytical model. The simulation modelling of antenna and accuracy characteristics of the antenna array has shown the necessity to take into account stochastic changes in APD and APFR under the influence of destructive factors. On the basis of the obtained dependences and values of accuracy characteristics it is possible to form the main provisions of the compensation method based on the input of corrections in the channels by amplitude and phase according to the results of the analysis of accuracy characteristics.
