<p>PURPOSE:To eliminate disturbance signals with object signals maintained constantly within an equal distance gate by a method wherein a transmission/ receiving interval is varied per pulse or every several pulses and received data is arranged to process signals synchronizingly. CONSTITUTION:A range gate number increase/decrease generator 11 and an adder 12 are provided between a PRF (pulse repetition frequency) identifier 17 and a timing control circuit 14, so that a data arranging circuit 6 and a range gate control circuit 13 for controlling said circuit 6 are added to output of a buffer memory 5. In order to vary a transmitting/receiving pulse interval per pulse or every several pulses with hardly changing a signal detection range, the PRF from a data processor 15 is synthesized by the range gate increase/ decrease generator 11 and the adder 12 and sent to a timing control circuit 14 while it is sent to the range gate control circuit 13. This permits data to be re-arranged in synchronism with change in transmitted PRF to prevent tracking of a disturbing device which follows at high speed and to track only object signals.</p> |
