At the end of the issuance of data from the sequential storage device 7, several times the issuing of the same data is repeated, but the data is issued from the random access memory 6.

The synchronizer 4 also carries out the formation of the clock signal, which is issued through the buffer amplifier 15. The signal of the zero position of the antenna and the signal of the increment of the angular position of the antenna form, l

- 12 are driven respectively by the driver 12 of the signal of the zero position of the antenna and the driver 13 of the signal of the increment of the angular position of the antenna and are issued through the first and second differential linear shapers 26 and 27, respectively.
