RADAR Russian patent published in 1997 - IPC

FIELD: radiolocation. SUBSTANCE: invention can be used in systems determining azimuth of target. Increased precision of determination of azimuth by radar is achieved by insertion into it of two-beam indicator, unit of two fibre-optical rules, unit of two photoelectric multipliers, subtracter, unit of two selectors and coincidence element. Signals from output of two-beam indicator go to inputs of fibre-optical rules which are optically matched to unit of photoelectric multipliers. First and second outputs of this unit are connected to proper inputs of unit of two selectors which outputs are brought to input of coincidence element having output connected to first input of plan-position indicator. Apart from this signals from outputs of unit of two photoelectric multipliers passing through subtracter sum up with signals of transmitting selsyn and go to receiving selsyn deflecting sweep of position indicator by value proportional to azimuthal deviation of target from zone of equal signal. EFFECT: increased precision of determination of azimuth by given radar. 2 dwg
