Generation and Processing of Chaotic Signals in Range Measurement Systems Chaos Generators as Cw Ranging Signal Sources

چکیده
In this paper the application of chaotic signals in continuous wave (CW) ranging systems is addressed. Diierent chaos generators that can be applied in this application are presented and analysed with respect to their signal properties. In the case of a CW ranging system the important requirement is an unambigu-ous range estimation. If classical correlation processing is applied in the CW ranging system, the capability of the ranging signal for unambiguous range estimation is analysed by means of the Woodward Ambiguity Function (WAF). A discrete time chaotic ranging system is presented and it performance with respect to multi user operation (CDMA) is analysed. A CW ranging system emits a ranging signal x t into a medium where targets at radial range from the ranging system r i , which are possibly moving with radial velocity v i relative to the ranging system, are present. These signal waves propagate

Chaotic Signals for Cw-ranging Systems - a Baseband System Model for Distance and Bearing Estimation
In this paper the application of chaotic signals in ranging systems is addressed. In [1] the idea of using chaotic signals as ranging signals in continuous wave (CW) systems has been introduced and motivated. Possible benefits where also analysed. This paper describes realisation and signal processing problems in chaos based range and bearing estimation. All the signal processing is performed i...
متن کاملNonlinear Multiuser Receiver for Optimized Chaos-Based DS-CDMA Systems
Chaos based communications have drawn increasing attention over the past years. Chaotic signals are derived from non-linear dynamic systems. They are aperiodic, broadband and deterministic signals that appear random in the time domain. Because of these properties, chaotic signals have been proposed to generate spreading sequences for wide-band secure communication recently. Like conventional DS...
متن کاملRandom Number Generators Founded on Signal and Information Theory
The strength of a cryptographic function depends on the amount of entropy in the cryptovariables that are used as keys. Using a large key length with a strong algorithm is false comfort if the amount of entropy in the key is small. Unfortunately the amount of entropy driving a cryptographic function is usually overestimated, as entropy is confused with much weaker correlation properties and the...
متن کاملGrid Impedance Estimation Using Several Short-Term Low Power Signal Injections
In this paper, a signal processing method is proposed to estimate the low and high-frequency impedances of power systems using several short-term low power signal injections for a frequency range of 0-150 kHz. This frequency range is very important, and thusso it is considered in the analysis of power quality issues of smart grids. The impedance estimation is used in many power system applicati...
متن کاملConservative chaotic flow generated via a pseudo-linear system
Analysis of nonlinear autonomous systems has been a popular field of study in recent decades. As an interesting nonlinear behavior, chaotic dynamics has been intensively investigated since Lorenz discovered the first physical evidence of chaos in his famous equations. Although many chaotic systems have been ever reported in the literature, a systematic and qualitative approach for chaos generat...
