FIELD: radiolocation, radio navigation, systems measuring angular positions. SUBSTANCE: two-plane direction finder has two identical antennas with commutated radiation patterns, two single-channel receivers, two angular discriminators, instruction former common for two channels. Decreased influence of fluctuations of amplitude of received signal on precision of determination of angular position is achieved by insertion of two units of data correction. Inputs of each unit are connected to outputs of receivers of both channels of direction finder. Outputs of units are connected to inputs of proper angular discriminator. EFFECT: decreased influence of fluctuation of amplitude of received signal on precision of determination of angular position of signal source. 1 dwg |
