Waveforms normally encountered in radar are essentially time-limited and band-limited. (With proper interpretation, this characterization also applies to CW radar systems.) Those familiar with Fourier transform theory will realize, of course, that a waveform cannot be simultaneously time and band-limited. But in many practical cases this approximation permits a better understanding of radar performance and simplifies calculations. Hence we shall be interested in approximate mathematical representations based on this assumption.
