Sparse frequency LFM ladar signals.
Through modeling we explored the possibility of utilizing a sparse frequency linear frequency modulation (LFM) signal for laser radar (ladar) applications. We propose a potential transmit and receive experiment utilizing the superposition of two LFM laser sources with a known difference frequency to provide the necessary segmented bandwidth. Finally we analyzed the signal performance of the pro...

15 صفحه اولA Detection and Parameter Estimation Method of Multicomponent LFM Signals Based on Reassigned S-Hough Transform
LFM signals are widely used in the fields of radar and communication etc., which make signals detection and parameters estimation a very important technology in multicomponent LFM signals. To solve the problems of error detection caused by the cross-terms in WVD-Hough methods and other modified WVD distribution methods, and low parameter estimation precision due to poor timefrequency concentrat...
متن کاملGeneralized Parseval’s Theorem on Fractional Fourier Transform for Discrete Signals and Filtering of LFM Signals
This paper investigates the generalized Parseval’s theorem of fractional Fourier transform (FRFT) for concentrated data. Also, in the framework of multiple FRFT domains, Parseval’s theorem reduces to an inequality with lower and upper bounds associated with FRFT parameters, named as generalized Parseval’s theorem by us. These results theoretically provide potential valuable applications in filt...
متن کاملDesign of Optimum Weighting Functions for LFM Signals
Linear frequency-modulated (LFM) pulse signals are probably the most common type of pulse compression waveforms for various radar systems (Barton, 2005; Cook&Bernfeld, 1967; Curlander & McDonough, 1991; Levanon & Mozeson, 2004; Richards, 2005; Skolnik, 2008). LFM signals are also often the waveform of choice for wideband systems, where the required bandwidth may be hundreds of megahertz. The am...
