Mismatched filter applied to complementary code design

Complementary code pairs have zero range sidelobe property, which is useful in radar applications to avoid stationary range sidelobe interferences. However, complementary code pairs exist only for limited codeword lengths. The general idea of complementary code design is extended in this paper by applying a mismatched filter procedure to the binary phase codeword pairs. Binary phase codeword pairs and the related mismatched filter impulse response coefficients are designed to fulfill the zero sidelobe property.
