WebTo get a better look, compare the 3-D ambiguity plots side by side. The ambiguity function is slightly skewed along the Doppler-Delay plane, which shows that slight changes in Doppler can cause errors in range measurements. This phenomenon is called range-Doppler coupling and occurs commonly in linear FM waveforms. WebAlso, AM waveforms are fairly easy to demodulate. Overall, then, AM can be viewed as a simple, low-cost modulation scheme. As usual, though, simplicity and low cost are accompanied by performance compromises—we never expect the easier, cheaper solution to be the best one. ... a PM waveform is simply a shifted version of a corresponding FM ...
