Some measurement techniques to determine compact range RCS accuracy

The author presents an overview of four measurements which are periodically being done in the OSU Compact Range. The first technique is field probing. The second method of range accuracy measurement involves signature measurements of several sizes of calibration targets. The third measurement involves the use of a large tilted flat metal plate whose bistatic scattering beam can be pointed at a region of the room to sense error sources. The fourth measurement technique involves pattern and signature measurements of generic low RCS (radar cross section) test targets. The contrasting areas of accuracy sensitivity for the four techniques are discussed.<>
