ANTENNA CROSS Russian patent published in 2000 - IPC

FIELD: radiolocation, determination of coordinates of emitting objects. SUBSTANCE: antenna cross includes main antenna and two common groups of base antennas uniformly distributed along straight lines crossing in space at right angle, units for group integration of signals and their group separation, unit for synthesis of pulse signals, unit for channel separation of signals and unit for identification of signals. Signals of main antenna and two common groups of base antennas are merged into one group of signals with injection of coherent frequency shifts into signals. Later group of signals is divided into three groups and signals of each group are summed to form pulse sequences which positions in first and second time frames manifest angles of arrival of signals to antennas. Finally these pulses are separated and mutually identified. Structurally antennas are arranged in the form of cross. EFFECT: increased informativity and speed of response thanks to coherent frequency and time division multiplex. 3 cl, 7 dwg
