A Mathematical Analysis of Polarimetric Phase and Amplitude with Frequency Agility for Radar Target Acquisition.
Abstract
Target models have been used to generate a mathematical analysis of the output voltage from a frequency agile radar with polarimetric processing. The purpose of the investigation was to determine the usefulness of such a system for target acquisition. It is shown that frequency agility provides a frequency spectrum at the output which is characteristic of the major reflecting centers illuminated by the radar. Polarimetric processing is not required to obtain this information. It is shown that each pair of individual reflectors contributes a frequency to the Fourier transformed signal. For a linearly frequency modulated waveform, this frequency depends on the difference in radar range between the two reflectors, the bandwidth of the transmitter, and the repetition period of the LFM waveform.
