As a side note, there is also something called periodic ambiguity function which is designed for cw signals, but Phased Array System Toolbox currently doesn't offer that.

There is more than one ambiguity function, this is the wide band single transmitter single receiver version. Most people think Doppler is just a frequency shift but it is actually a time dilation, although the frequency shift model is very often sufficient, particularly when looking at steady lines like molecular emission lines.

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. As indicated in the notation, the independent variables of the ambiguity function are time (W) and frequency (f). The time The ambiguity function of a waveform represents exactly the output of the matched filter when the specified waveform is used as the filter input.

Matched Filtering and Ambiguity Function. Compare Ambiguity Functions for Different Wave Modulation Schemes. 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.

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. Comprehensive help is included.

2021-04-24 · The high-order ambiguity function (HAF) is a nonlinear operator designed to detect, estimate, and classify complex signals whose phase is a polynomial function of time. The HAF algorithm, introduced by Peleg and Porat (1991), estimates the phase parameters of polynomial-phase signals measured in noise. The purpose of this correspondence is to analyze the asymptotic accuracy of the HAF
