AZIMUTH DISPLAY APPARATUS

PURPOSE:To simplify a structure and to perform the adjustment of a phase by an electronic means, by reading amplitude data in synchronous relation to the rotation of a goniometer to obtain two equilibrium modulation signals each having amplitude phase. CONSTITUTION:A count output signal is applied to memories 11A, 11B of an azimuth display apparatus 9 from an address counter 12 to repeatedly read addresses from the leading address to the final one. A pulse CK2, which is outputted in the resolving power at every 0.2 deg. obtained from a rotary encoder 4, is applied to the address counter 12 so that the reading cycle is coincided with the rotary cycle of a high frequency goniometer 2 and the count output thereof is applied to the memories 11A, 11B as an address signal and the address counter 12 is reset by a pulse CK1 generated every when the goniometer 2 rotates one time, so that the rotation of the goniometer 2 and the relation of the reading cycles of the memories 11A, 11B are always coincided.
