PHASE CONTROLLER FOR WAVE RECEIVER

PURPOSE:To improve the resolution of an object image, by receiving waves from the object, which is placed in an optional position, in the same phase by plural wave receivers. CONSTITUTION:A receiving signal from a wave receiver 1 is converted to a digital signal by an A/D converter 3. Meanwhile, a prescrived clock pulse from a clock pulse generating circuit 4 is selected by a selecting circuit 5, and a timing for digital conversion is generated by a timing generating circuit 6. The second and following timings are selected by data obtained by setting a value, which is resulted from the subtraction of a prescribed balue from the first timing designation data, to a latch 7. When the number of timings coincides with a value set to a memory 12, a coincidence detecting circuit 13 generates the output to update the subtracter of a latch 10 by a memory 9.
