Radar reflectivity measurements go back to the earliest days of radar. What are now known as RCS measurements began to be more openly discussed in the literature in the late 1950s and early 1960s (l3achrnan [133], Cummings [1313], Currie, Curie [1315], Johnson et al. [B38], Kennedy [1340]. Proceedings of the IEEE [860]), although much of that work was under the auspices of the military and thus not readily available. This situation began to change with the 1965 publication of a Special Issue of the Proceedings of the IEEE jB6l], which concentrated on topics associated with radar ref’ectivity. Several of the 1965 papers in this issue specifically focused on the requirements of RCS measurements, including an overview of the state of the art in RCS measurements (Blacksmith et al. [B7j. [B81). In addition, this issue included papers on range requirements (Kouyoumjian. Peters [B50j), target support issues (Freeny 1B261). measurement techniques (Bachman [B3], Huynen [B29]), and discussions of typical facilities, both static (Marlow ci al. [ 854]) and dynamic (Olin, Queen [B59]). With the publication of this issue, a growing open-source literature base on RCS measurements became available to practitioners in the field.
The ensuing period marked the beginnings of two measurement trends: the rapid development of new approaches to making measurements, and measuring targets with low RCS. There was a major push to reduce significantly the radar scattering from military vehicles. Along with the objective to produce vehicles with reduced RCS came the requirement to measure these smaller signal levels accurately. In addition, many applications required the full complex polarimetric scattering matrix. Thus, significant efforts were made to improve the technology of RCS measurements, including increasing the dynamic range of the measurement system and adding complex phasor measurements.
During this same time period, significant research was being conducted on the theory of electromagnetic scattering. Universities such as Syracuse University, the University of Michigan. The Ohio State University, and the Georgia Institute of Technology were engaged in understanding the foundations of scattering, with the objectives of taking better measurements and being able to predict analytically and numerically the scattering from increasingly complex objects. During this period, increased computational power allowed tools like the method of moments (MOM) (Harrington [1328]), the geometrical theory of diffraction (GTD) (Keller [B39]), physical optics (P0)) (Ufimtsev, Senior [B69]), and the physical theory of diffraction (PTD) (Ufimtscv [B68j) to be used for realistic scenarios.
