Abstract :
The ambiguity function, which is used to determine the target resolution and parameter estimation capabilities of a radar, of discrete-time signals is discussed. Both continuous-time, continuous-frequency and discrete-time, discrete-frequency ambiguity functions are presented. To avoid aliasing, it is shown that the sampling rate must be twice the Nyquist rate associated with the sampled signal
