Abstract :
Step frequency waveforms have been used in measurement radars in anechoic chambers for high resolution imaging of stationary or rotating targets in one or two dimensions. However in operational scenarios such as detection of moving targets, frequency step waveform spreads the target return and shifts the target range resulting in a loss of target magnitude, range accuracy and range resolution. This paper models target return, brings out the problems associated with step frequency waveform and then describes a method for detection of moving target in the presence of clutter. Also discussed are step frequency waveform design considerations
