摘要：
Aimed at the problem of over-high side-lobes of the matched filter response of common radar signals, we propose a new NLFM signal with ultra-low side-lobes. The new frequency modulation function is a Tangent function with its parameters determined experimentally. The simulation results suggest the new side-lobe level has been improved by at least 10dB. In this paper, we thoroughly analyze the main-lobe width, Doppler tolerance, the effect of the sampling rate and the compression rate of this new NLFM signal. Its ambiguity function is also plotted and analyzed. In the end, the consisting problems are discussed, too.
