Abstract

The ambiguity diagram is a measure of the sonar or radar properties of a given echolocation signal. It consists of a three-dimensional graph in which the x and y axes represent range and velocity, and the height at any point is the probability of a target having the corresponding range/velocity co-ordinates. Each section through the diagram parallel to the range axis represents the output of an ideal, range measuring receiver (eg. matched filter or correlation receiver) in response to an undistorted, energy normalised echo from a target moving at the velocity corresponding to that section; this output is the cross-correlation function of the transmitted signal and a doppler shifted copy of the transmitted signal. Each section through the diagram parallel to the velocity axis represents the output of an ideal velocity measuring receiver (eg. Fourier Transform receiver) in response to an undistorted, energy normalised echo from a target at the range corresponding to that section.
