Abstract
An indoor method for measuring the radar cross section of objects by modulating the position of the object is described. The use of synchronous detection and employment of a substitution technique wherein the scattering from an object under test and a known object are measured and compared simultaneously reduce measurement error to ±2 per cent. The characteristics of the system are discussed, and its advantages and limitations are compared with other systems. Measured curves for the back-scattering cross-section of dipoles for lengths from 0.4λ to 1.6λ show good agreement with other published theoretical and experimental curves. Methods for measuring back-scattering and off-angle scattering from irregular objects by extension of this technique are indicated.Keywords
