Regarding the periodic ambiguity function (PAF): If you want to choose one of the preset signals, but wish to plot the PAF when the processor is matched to several periods of the signal (e.g., 4 periods), then you can do the following: In the GUI choose the desired signal and click on the "Cal&Plot Sig." button. In pulsed radar and sonar signal processing, an ambiguity function is a two-dimensional function of propagation delay and Doppler frequency, (,). It represents the distortion of a returned pulse due to the receiver matched filter [1] (commonly, but not exclusively, used in pulse compression radar) of the return from a moving target.

At this point, there is perfect correspondence between the received waveform and the matched filter. The maximum value of the normalized ambiguity function is one. We now turn our attention to the ambiguity function. The ambiguity function, which is denoted as FW f,, is primarily used to gain an understanding of how a signal processor responds, or reacts, to a given returned signal.
This example shows how to visualize and interpret different waveform processing schemes and their tradeoffs in the Radar Waveform Analyzer app. Matched Filtering. Matched filtering increases SNR and improves detection.

Ambiguity (pronounced am-big-YOU-it-tee) is the presence of two or more possible meanings in a single passage. The word comes from a Latin term which means, "wandering about" and the adjective form of the word is ambiguous. Other terms used for ambiguity are amphibologia, amphibolia, and semantic ambiguity.

In the context of the STFT, the ambiguity function is known to play an important role in the estimation of optimal localization properties in many different areas, e.g., for operator approximation by Gabor multipliers or for RADAR and coding applications [7, 2, 18]. The new version plots the ambiguity function of any input signal. It is improved version of the previous function for plotting the ambiguity function I've posted. The axis estimation and plotting is included. Some verification was made.
