Ambiguity functions and their associated uncertainty functions, play a central role in echo-location as they relate signal characteristics to system and parameter estimation performance.

Vector-valued CAZACs are relevant in light of vector sensor and MIMO technologies. The goal is to de ne the discrete vector-valued ambiguity function. Our notion of frame multiplication allows us to make this de nition. The theory and relevance of such ambiguity functions is developed, including computation 2020-02-06 · In this article, the generalized ambiguity function (GAF) for an MIMO-radar system is derived by using a set of quasi-orthogonal step-frequency UWB-throb signals.

Ambiguity function

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. This exact representation makes the ambiguity function a popular tool for designing and analyzing waveforms. Ambiguity functions and their associated uncertainty functions, play a central role in echo-location as they relate signal characteristics to system and parameter estimation performance. Estimation performance as measured by the CR bound was shown in the previous chapter to be proportional to the resolution or “peakedness” of the ambiguity function (AF).

The magnitude of the ambiguity function achieves maximum value at (0,0). At this point, there is perfect correspondence between the received waveform and the matched filter.

The ambiguity function is used in radar systems to get the distance and the relative speed of a moving object with respect to the transmitter. Is called ambiguity because it also tells about the ability to distinguish objects that are close between them and with a similar vector velocity.
