THE HP 85108 ASA HIGH PERFORMANCE ANTENNA AND RADAR CROSS-SECTION ANALYZER John W. Boyles Network Measurements Division 1400 Fountaingrove Parkway Santa Rosa, California 95403 RF & Microwave Measurement Symposium and Exhibition Flin- HEWLETT ~~ PACKARD www.HPARCHIVE.com ANTENNA AND RCS TESTING WITH THE' HP 8510B NETWORK ANALYZER John W. Boyles Network Measurements Division 1400 Fountaingrove Parkway Santa Rosa, CA 95401 ABSTRACT: The HP 8510B Network Analyzer contains enhancements and new features that expand its scope beyond network analysis to include new capability for high performance Antenna and Radar Cross-Section (RCS) Testing. This paper describes different measurement techniques used for Antenna and RCS testing including the use of Far-Field, Near-Field, and Compact Antenna and RCS test ranges. The unique requirements that these measurement techniques place on the instrumentation and how they are satisfied by the appropriate HP 8510B configuration are discussed. Other topics include descriptions of the harmonic sampler (HP 8511A) and external mixer based front ends for the HP 8510B and the use of software (time domain) and hardware gating techniques to remove RCS range clutter. Author: John W. Boyles is a development engineer at the Network Measurements Division of Hewlett-Packard located in Santa Rosa, CA. He has a BS degree received from North Carolina State University in 1978 and a MSEE degree received from the Georgia Institute of Technology in 1979, both in electrical engineering. With HP since 1979, he has performed both microwave oscillator and analog circuit design and has developed training materials on time domain network analysis. Since 1984, he has been involved in application and system development for Antenna and Radar-Cross Section Measurements with High Performance Vector Analyzers. 3 www.HPARCHIVE.com Antenna and Radar Cross Section (RCS) measurements are performed in a variety of ways, each of which presents unique challenges to the test instrumentation and measurement system. While there are several different kinds of antenna and RCS test ranges, the required test equipment does not change significantly
