摘要

In this thesis, the Step Frequency radar system is compared with the conventionalConstant Frequency. radar system. The two radar systems are separately analyzed and their analyses are followed by a comparison which is mainly based upon their effectiveness to detect moving targets in clutter. The step frequency waveform consists of a series of pulses whose pulse width is constant and whose carrier frequency is linearly increased from pulse to pulse in steps. As compared to the conventional constant frequency radar waveforms, the step frequency waveform can achieve high range resolution while still retaining the advantages of lower instantaneous receiver bandwidth and lower analog-to-digital sampling rate at the expense, however, of more complex signal processing.
