摘 要:A uniform sidelobe level represents an optimum performance criterion in the design of pulse compression waveforms. A new form of pulse compression filter for polyphase codes is presented which generates a flat uniform sidelobe pattern similar to those obtainable from Barker codes. The sidelobe levels are decided solely by the length of the phase codes, which can be set arbitrarily. Their use involves a small loss and degradation in range resolution, but excellent Doppler tolerance.
