Sidelobe Level Reduction in the ACF of NLFM Signals Using the Smoothing Spline Method
Roohollah Ghavamirad, Ramezan Ali Sadeghzadeh, Mohammad Ali Sebt
The high level of sidelobes in the autocorrelation function of the nonlinear frequency modulation signal is a challenge. One of the conventional methods to reduce the sidelobe leve…
Range resolution improvement for two close targets by using the FM signals
Roohollah Ghavamirad, Ramezan Ali Sadeghzadeh, Mohammad Ali Sebt +1
In this paper, we have focused on the improvement of the range resolution of two close targets by using FM signal. Two algorithms comprise IFFT and MUSIC have been used to reach ou…
Sidelobe Level Reduction in ACF of NLFM Waveform
Roohollah Ghavamirad, Mohammad Ali Sebt
In this paper, an iterative method is proposed for nonlinear frequency modulation (NLFM) waveform design based on a constrained optimization problem using Lagrangian method. To dat…
Phase Improvement Algorithm for NLFM Waveform Design to Reduction of Sidelobe Level in Autocorrelation Function
Roohollah Ghavamirad, Mohammad Ali Sebt, Hossein Babashah
In this paper, a phase improvement algorithm has been developed to design the nonlinear frequency modulated (NLFM) signal for the four windows of Raised-Cosine, Taylor, Chebyshev,…
