Time-frequency representation of multicomponent chirp signals
نویسندگان
چکیده
This work deals with the analysis of chirp signals by means of time-frequency representation. We propose a chirp adapted time-frequency representation (CA) in which the interferences are significantly reduced. This method is applied to the analysis of acoustic echoes of a sphere target. Comparison of the results to other types of time-frequency distribution of the Cohen’s class shows that the identification of the signal features with CA representation is clearer than with other types of bilinear time-frequency distributions.

A Detection and Parameter Estimation Algorithm of Multicomponent Chirp Signals Based on Generalized S-Transform
The target echo of downward-looking radar can be simulated by a multicomponent Chirp signal with noise, which makes signal detection and parameter estimation a very important processing. Aiming at the problems of error detection caused by the cross-terms in WVDHough methods and other modified WVD distribution methods, and low precision due to poor time-frequency concentration in S-Hough transfo...
متن کاملJoint Estimation of Time-Frequency Signature and DOA Based on STFD for Multicomponent Chirp Signals
In the study of the joint estimation of time-frequency signature and direction of arrival (DOA) for multicomponent chirp signals, an estimation method based on spatial time-frequency distributions (STFDs) is proposed in this paper. Firstly, array signal model for multicomponent chirp signals is presented and then array processing is applied in time-frequency analysis to mitigate cross-terms. Ac...
متن کاملBottom backscattering coefficient estimation from wideband chirp sonar echoes by chirp adapted time-frequency representation
This work is concerned with the estimation of the bottom backscattering coefficient as a function of frequency and of incident angle. Generally, the backscattering coefficient is studied for a given frequency at various angle. But the backscattering depends not only on the angle, but also on the frequency. In our work, a wideband chirp sonar (20140kHz) with -3dB half-angle 12o has been used to ...
متن کاملFiltering in Time-Frequency Domain using STFrFT
The Fractional Fourier Transform is a generalized form of Fourier Transform, which can be interpreted as a rotation by angle ? in time-frequency plane or decomposition of signals in terms of chirps. However it fails in locating Fractional Fourier Domain Frequency contents. Short-time FRFT variants are suitable for analysis of multicomponent and non-linear chirp signals with improved time-freque...
متن کاملFiltering in the joint time/chirp-rate domain for separation of quadratic and cubic phase chirp signals
This article investigates the possibility and convenience of a filtering operation in the joint time/chirp-rate (TCR) domain, and proposes a novel linear TCR filter for decomposing multicomponent signals into their quadratic and/ or cubic phase chirp components with monotonic instantaneous chirp-rate (ICR) laws only. The TCR domain mask of the filter is selected on a display of a TCR representa...
