Pulse compression filter generating optimal uniform range sidelobe level

A uniform sidelobe level represents an optimum performance criterion in the design of pulse compression waveforms. A new form of pulse compression fil ter for polyphase codes is presented which generates a flat uniform sidelob e pattern similar to those obtainable from Barker codes. The sidelobe level s are decided solely by the length of the phase codes, which can be set arb itrarily. Their use involves a small loss and degradation in range resoluti on, but excellent Doppler tolerance.
