Optimal sidelobe suppression for biphase codes

A technique is developed for the generation of filters for pulse compression sidelobe reduction in radar systems. This technique has two advantages over the standard Wiener filtering technique: it minimizes sidelobe energy over multiple input sequences, and it can shape the sidelobe energy through the application of a weighting function that indicates which sidelobes are most important to reduce. Two example applications are provided, showing the effectiveness of this technique in generating filters for orthogonal code pairs and in generating filters for compressions with low sidelobes near the main peak.<>
