Abstract
A pulse compression signal processor suitable for use in a phase-coded, pulse compression radar for decoding the phase coded radar return pulses to enhance the resolvability of objects in range is disclosed. The pulse compression signal processor includes a conventional correlation processor operative in accordance with an initial filter function to convert a signal representative of the phase-code of the transmittal RF pulse to effect the range correlation response thereof. The resulting range correlation response is modified in accordance with a desired range correlation response. Both the phase code representative signal and the desired range correlation response signal are converted by fast Fourier transformations into their corresponding frequency domain signals which are divided to effect a desired filter function signal for use in decoding the phase-coded radar return pulses to effect substantially the desired range correlation response thereof. The pulse compression signal processor further includes an interative process to truncate the desired filter function signal in time in accordance with pre-established criteria.
