There are two kinds of indoor RCS test chamber: compact and otherwise. The compact range relies on an antenna that is so large that all test objects measured in the chamber are in the near field of the antenna. The antennas used in all other indoor chambers are much smaller, with the consequence that the far-field criterion developed in Chapter 4 is just as much a consideration in those chambers as it is outdoors. The differences in the design and operation of the two kinds of chamber are great enough that we treat them in separate chapters. We discuss all others in this chapter, reserving Chapter 8 for compact ranges.
