Abstract: PURPOSE:To remove an interference wave without exerting any influence upon data by finding a level difference between a last signal and a signal right before the last signal which are obtained at the same distance, and comparing the difference with a comparison value and handling the last data as corresponding- distance data according to whether the difference is larger or not. CONSTITUTION:A video signal obtained by a radar receiver is quantized and data of each range pin is stored in the 2nd memory 17 having 1PRF (one radar pulse) capacity. Next 1PRF data is also stored in the 1st memory 16. Then, when current data A is inputted, the last data B and data C right before the last data are processed by the subtraction of a subtracter 19. This subtraction is carried out by reading signal of the same distance out of memories 16 and 17 to a register 18. This subtraction result is made into an absolute value by an absolute value circuit 20 and this is compared by a comparator 21 with a value Z set by a comparison value setter 22. Then, a data range detected from whether or not the comparison value is larger or not is compensated by employing of data of the same distance which is 1PRF before.
