Abstract

This paper presents the Nonlinear Frequency Modulation (NLFM)-Costas hybrid signal with the complex methods of interpulse Costas frequency coded modulation and intrapulse Nonlinear Frequency Modulation (NLFM). The signal construction is analyzed in theory and four critical parameters are obtained, such as Power Spectrum Density (PSD), ambiguity function, Peak Sidelobe Level (PSL) and Integral Sidelobe Level (ISL). The experimental results show that the NLFM-Costas hybrid signal has the "thumbtack" ambiguity function and better autocorrelation property. The NLFM-Costas signal can achieve better RF stealth performance than NLFM signal or Costas signal or LFM-Costas hybrid signal and it has good application prospects in modern battlefield environment.
