Optimal peak sidelobe filters for biphase pulse compression

A technique for the generation of mismatched filters that minimize the peak sidelobe in the correlation of a biphase code is developed. The technique is applied to several well-known codes, and the resulting sidelobe performance is compared to that of the matched filter and optimal integrated sidelobe level filter. The theory is shown to be applicable to the generation of filters that produce regions within the correlation that are nearly sidelobe-free. These filters may be of use in tracking applications and some specialized surveillance scenarios.<
