Ambiguity Function or Auto-Ambiguity Function. Ambiguity Function is used for determining the characteristics of the designed waveform in respect of measurement accuracy, ambiguities in range and velocity, and target resolution. [10].

the ambiguity function. A general result is established for annihilating sets : strongly/weakly annihilating sets for the Fourier transform yield such sets for the ambiguity function, extending a result known for sets of finite measure. We apply this to sublevel sets of nondegenerate quadratic forms. Chapter 5 The Ambiguity Function - Analog Waveforms 5.1.

(T, v) = x(T, v)2 = Js(t)s*(t. Jul 9, 2004 Summary The ambiguity function (AF) represents the time response of a filter matched to a given finite energy signal, when the signal is  The radar ambiguity function represents the output of the matched filter, and it describes the interference caused by the range and/or Doppler shift of a tar-. In pulsed radar and sonar signal processing, an ambiguity function is a two- dimensional function of propagation delay τ {\displaystyle \tau } \tau and Doppler   Woodward's ambiguity function (AF) like periodic autocorrelation relates to autocorrelation. AF is defined for a finite signal, processed by its matched filter.

Wasow et al. (2005) also suggest ambiguity might be use-ful in language contact situations, where speakers of both languages should ideally be able to handle words meaning two different things in two different situations. They also point out that ambiguity does sometimes serve a commu-nicative function when speakers wish to be ambiguous

A Complex-Ambiguity Function Approach to a GPS Receiver. J. York, J. Little, D. Munton, K. Barrientos https://www.ion.org/publications/pdf.cfm?articleID=8677  

The ambiguity function is a major tool for studying and analyzing radar signals. It will be used extensively in the following chapters, where different signals will be described. The chapter presents four important properties of the ambiguity function and proves them. Ambiguity Function is possible to get the system impulse response, which is used for synthetic aperture radar image formation, that is the inverse process of the raw data or level zero data generation. A scheme for the generation of the impulse response function using the AF is presented in Fig. 1, where m is the time delay and k is the frequency The ambiguity function of a waveform composed of recurrent pulses with period T R is of the bed of nails type. Practically all the energy is concentrated in the correlation peaks.

Section II reviews the de Þ nition of the MIMO radar ambiguity function. Section III derives the properties of the MIMO radar ambiguity function, and Section IV concludes the paper. 1 Work supported in parts by the ONR grant N00014-06-1-0011, and the 2021-03-29 · Metadata. Abstract: Calculation of the complex ambiguity function is viewed as the basis for joint estimation of the differential delay and differential frequency offset between two waveforms that contain a common component plus additive noise. ambiguity function through the cros-correlation of s(&fo) with s(t+,r fojf), where r and f are the time delay and Me doppler shif Generally, the function is characterized by X (rf) f u*(t)u(t + ) exp (- j2 r ft) dt (2) where u(t) is the complex coqjugate of u(t).
