Nonlinear FM waveform design to reduction of sidelobe level in autocorrelation function
TL;DR: In this paper, the variation of peak sidelobe level with regard to mainlobe width for these four different window functions are analyzed and the results of power spectral density obtained from the simulation and the desired PSD are compared.
Journal ArticleDOI
Evaluation of a class of NLFM radar signals
TL;DR: From this analysis, it is found that the OPFS model proposed in this paper outperforms all other contenders for most combinations of the objective functions and is expected to be better than nearly all signals within the entire search set.

Sidelobe suppression on pulse compression using curve-shaped nonlinear frequency modulation
TL;DR: This paper presents a developed curve-shaped Nonlinear Frequency Modulation (NLFM) using second degree polynomial approach for radar pulse compression in order to reduce the sidelobe level.
Proceedings ArticleDOI
Performance analysis of curve-shaped NLFM against Doppler effect and background noise
TL;DR: The curve-shaped nonlinear frequency modulation (NLFM) has been developed for overcoming this lack and prior investigation showed that this method provide lower sidelobe suppression than LFM as mentioned in this paper.

On Estimating Nonlinear Frequency Modulated Radar Signals in Low SNR Environments
TL;DR: This article proposes to improve the noise resilience of the radar signal estimation by constraining the estimate to be in a low-dimensional signal space, and focuses on estimating nonlinear frequency modulated radar signals that have good target resolution characteristics.

On the use of windows for harmonic analysis with the discrete Fourier transform
TL;DR: A comprehensive catalog of data windows along with their significant performance parameters from which the different windows can be compared is included, and an example demonstrates the use and value of windows to resolve closely spaced harmonic signals characterized by large differences in amplitude.

Optimum Mismatched Filters for Sidelobe Suppression
Martin H. Ackroyd,F. Ghani +1 more
TL;DR: In this article, the application of least-mean-squares approximate inverse filtering techniques to radar range sidelobe reduction is discussed, and a filter which completely suppresses the range sidelobes of a 13-element Barker sequence is only 0.2 dB worse than a matched filter in noise.

On the design of optimum radar waveforms for clutter rejection
D. DeLong,E. Hofstetter +1 more
TL;DR: The problem to be considered in this paper is that of designing radar signals and receivers that are optimum for detecting a point target masked by a background of clutter returns and thermal noise.
Journal ArticleDOI
The design of FM pulse compression signals
TL;DR: The design procedure, which is based upon an approximate analysis, gives best results when the duration-bandwidth product of the signal is large, and it is therefore useful in the design of pulse compression signals.
Journal ArticleDOI
Sidelobe reduction via adaptive FIR filtering in SAR imagery
TL;DR: Adapt sidelobe reduction (ASR) provides a single-realization complex-valued estimate of the Fourier transform that suppresses sidelobes and noise, which is critical for large multidimensional problems such as synthetic aperture radar (SAR) image formation.
