FIELD: radio, communication.SUBSTANCE: in control centre of the radar system at specified intervals the group of radar stations (RS) is selected, which carrier frequencies are within one of the sub-bands of on-board means of interferences (BMI), and the angles of viewing relative to the line of the object course when viewed from the centre of the area of uncertainty does not exceed the half-width of BMI working sectors, the area of uncertainty of object position is divided into sub-areas so that each sub-area fits into the main lobes of the antenna directional patterns of all selected RS, the sensing time of each sub-area is specified with the selected RS, the angular coordinates of sensing are calculated by the selected RS, the frequencies of emitted RS signals is selected at random within frequency sub-band of the BMI, and the minimum difference of carrier frequencies for all possible pairs of the selected RSs should exceed half the sum of values of the width of the spectra of the sensing RS signals, the data on time, angular and frequency sensing parameters are directed to the selected RSs.EFFECT: improving quality of detection and tracking of air objects.6 dwg |
