ABSTRACT

The formula for the output of the matched filter was derived in Chapter 4, and it is, assuming a moving target with Doppler frequency ,

The modulus square of Eq. (5.1) is referred to as the ambiguity function. That is,

The radar ambiguity function is normally used by radar designers as a means of studying different waveforms. It can provide insight about how different radar waveforms may be suitable for the various radar applications. It is also used to determine the range and Doppler resolutions for a specific radar waveform. The three-dimensional (3-D) plot of the ambiguity function versus frequency and time delay is called the radar ambiguity diagram.
