摘要
In a single channel medium PRF pulse doppler radar receiver, the return signal data is processed to prevent sidelobe return signals from being displayed and rejects ground moving targets up to approximately 80 knots while having no high velocity blind speeds. After the returns are filtered by a doppler filter notch for rejecting returns having a velocity substantially less than the 80 knot example, the return data undergoes three stages of correlations to reject sidelobe returns, and undergoes processing including a fourth correlation which enables the third stage of correlation to output a signal only for unambiguous ranges that contain target data in excess of the 80 knot range.
