FIGURE 4.20 A portion of the ambiguity function for the pulse burst waveform
with M = 5 and T = 4τ. Positive frequencies only shown.

Figure 4.21 is a diagram of the structure of the central peak of the pulse
burst ambiguity function and the first repeated peaks in Doppler and range. This
figure summarizes how the various waveform parameters determine the

resolution in range and Doppler, the range ambiguity interval, and the blind
Doppler interval. The individual pulse length τ is chosen to achieve the desired
range resolution (cτ/2 meters). The pulse repetition interval T sets the ambiguity
interval in range (cT/2 meters) and the blind interval in Doppler (1/T Hz).
Finally, once the PRI is chosen, the number of pulses in the burst determines the
Doppler resolution (1/MT Hz).
