Abstract :
Three distinct methods of making high-range resolution radar cross-section (RCS) measurements are discussed. Comparisons are drawn for nanosecond pulse, FM/CW, and frequency-stepping methods of measuring location and magnitude of discrete scattering sources. The effects of using wide bandwidth transmissions on RCS amplitude level and fine structure are quantitatively estimated, and analytical results are presented. The three techniques are effective and yield the desired information about the magnitude and location of discrete scattering sources. Minor differences in data format and convenience of operation are noted, and it is concluded that a need for additional investigation of wide-band scattering phenomena is necessary.
