  • The mathematical expression of Continuous-Chaos Frequency-Modulating Signal (CCFMS) is given. The auto-correlation function and root-mean-square bandwidth of CCFMS are derived in theory. The results show that autocorrelation function of CCFMS has excellent side lobe suppression performance. Its RMS bandwidth is proportional to frequency modulation index and RMS of chaotic signal. The performance of CCFMS is further confirmed with typical chaos. It is found that CCFMS has high time peak to side lobe ratio, flat power spectrum, almost thumbtack ambiguity function and peak to average power ratio equal to that of sinusoidal signal. The performance of CCFMS radar against noise is analyzed. Compared with LFMS radar, CCFMS radar has obvious anti-jamming advantages with signal-to-interference ratio improvement factor increased by about 5.5 dB.
