What is cross ambiguity function?
The cross ambiguity function replaces one of the terms in (1) with another energy signal : Consider a radar-like signal consisting of a pulse with finite temporal support, such as a burst of a sine wave or a burst of a chirp waveform.
What is radar ambiguity?
The radar ambiguity function is defined as the absolute value of the envelope of the output of a matched filter when the input to the filter is a Doppler-shifted version of the original signal, to which the filter was matched. Ambiguity functions are usually analyzed on a single pulse basis.
