Mismatched multicarrier complementary spread spectrum radar and sonar systems

In this paper MC-SS radar or sonar concept that make it possible complementary sequences application is proposed. An ideal autocorrelation properties of this sequences are degraded for greater target speeds. To improve autocorrelation ambiguity function DIRLS algorithm for filter response shaping is applied.
