Possibility in Analyzing Real-time LFM Signals under Complex Jamming Conditions
Original language description
In this paper, a method for detecting and estimating the chirp rate and the pulse width of radar signals with linear frequency modulation based on the cross-correlation function under jamming conditions by continuous-wave signals and white noise is investigated. The proposed method includes two stages; the first is used to detect or estimate the chirp rate of the linear frequency modulation signal, and the second one is used to estimate the pulse width of this signal. In the first part of the paper, the accuracy of the method is studied by simulation a linear frequency modulation signal in the MATLAB environment to determine the lowest value of SNR, at which this technique is still able to detect and estimate the parameters of this signal. Based on the simulation results, a real-time signal is used to verify its functionality in the second part of this paper. The experimental results confirm that the proposed method can detect and estimate the parameters of linear frequency modulation signal under jamming conditions by continuous-wave signals and white Gaussian noise at the value of SNR > -7 dB.
