Books on the subject of ground penetrating radars provide definitions of pulse and stepped frequency radars, mentioning the structure of their signal and other technical details.
However, I was not able to find a source or comparison on practical results of those designs.
What are the practical differences between pulse and stepped frequency radars? Is there any difference in resolution, the complexity of hardware, attenuation, power consumption, signal processing...?
I'm asking this question because I am asked to design an imaging radar as homework and I cannot choose which method should I use, textbooks that I can find provide only technical background.
