What is ambiguity diagram?
An ambiguity diagram is a three-dimensional plot that shows the results of convolving a range of frequency-shifted signals with a fixed reference signal. DETAILED EXPLANATION: The Ambiguity diagram uses the waveform that is sent out by a RADAR as its reference waveform.
What is the use of ambiguity diagram?
The diagram that represents the ambiguity function is called the ambiguity diagram. It indicates the limitations and utility of particular classes of waveforms and gives a general guideline for the selection of suitable waveforms for various applications.
What is ambiguity function in radar?
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.
What is Doppler ambiguity?
In pulse radar, the modulation of the carrier frequency is a periodic sequence of rectangular pulses. The frequency spectrum of the transmitted signal is a comb-shaped line spectrum. The line spacing of the spectrum is equal to the Pulse Repetition Frequency fPRF or PRF.
