The application of time domain Prony´s method to three basic radar targets

Time-domain Prony´s method has been used to extract the dominant complex natural resonances of three simple radar targets: a conducting sphere, a finite cone and a finite right circular cylinder. The sliding window technique has been used to locate the consensus pole set. The effects of sampling interval, noise and polarization on the extraction process have been studied. The SNR has been studied with standard deviation of additive white gaussian noise as a variable parameter. The extraction process is sensitive to sampling rate. A reasonable and acceptable sampling interval has been found for each of these cases.
