N2 - This paper introduces a method which can improve accuracy for estimating parameters of linear frequency modulation (LFM) signal. The proposed approach is based on Short Time Fourier Transform (STFT). After STFT, spike filter and detecting threshold are used to achieve high precision of parameters estimation in the time domain. What's more, moving windows and frequency compensation are done to improve accuracy for frequency parameters estimation. Simulation results show that this method is effective in improving the accuracy for parameters estimation of LFM and requires only moderate computation ability. Thus it can be widely applied.
