THEORETICAL AND EXPERIMENTAL INVESTIGATION OF A TECHNIQUE FOR REDUCING EXTRANEOUS SIGNALS IN RADAR SCATTERING MEASUREMENTS

Abstract

The results of an investigation of analytical and analog techniques for reducing the influence of target support systems for radar scattering measurements are presented. An experimental system for analytically reducing the influence of target supports is implemented by incorporating a phase measurement system and a digital computer into an operational radar cross section measurement facility. Data are obtained by using the system to reduce the influence of the return of Styrofoam support columns during the measurement of 1/2-, 5/8-, 7/8-, and 2-inch diameter spheres and a 30-degree, 5.1-inch diameter sphere-cone as targets at L-Band. A cross section measurement error of about 7 db, resulting from the influence of the target support system, is reduced to about 1 db by using this discrimination system in the vicinity of nose-on in the case of the sphere-cone target. The discrimination system output is compared to a low background measurement on the sphere-cone.
