MEASUREMENT OF RADAR CROSS-SECTION OF CONDUCTORS OF ARBITRARY SHAPE BY IMAGE PLANE TECHNIQUE

Abstract

Radar cross-section measurement of conductors has been carried out in the laboratory using an Image .Plane. The methods used to measure the RCS, are (a) Standing wave ratio or S.W.R. method (b) Cancellation method. The experimental results are compared with those obtained theoritically for objects like sphere, cylinder, edges, thin wire, curved surface and a combi-nation of thin wire and a 'sphere. The ultimate objective is the measurement and theoritical verification of RCS of objects whose periphery donot coincide with the normal co—ordinate systems, that iso a complex object. Some advance towards this direction has been achieved and recorded in. the later part of the dissertation. Mostly the RCS in the reso-nance region was observed and frequency used was 8.2 to 12.4 GHz (X band). One experiment using, higher frequency i.e. 12.0 to 18 GHz (Ku band) has been carried out.
