ABSTRACT:
A pulse compressing apparatus for use in a radar system receives an input signal data stream which has been received by the radar system and which corresponds to a transmitted long pulse. A weight coefficient generator generates the same number of weight coefficients as the number of input signal values in the input signal data stream. The same number of arithmetic units is provided and the weight coefficients are sequentially transferred to each arithmetic means where they are processed with the input signal values. The results of the processing from the arithmetic units are added together to produce a compressed pulse output.
