Paper Abstract

The design of laser radars and the determination of the detectability of various vehicles require accurate data for the monostatic reflectivity of surface materials to far-field laser illumination at many different wavelengths. Monostatic bidirectional reflectance can be measured with an interferometric reflectometer using a homodyne arrangement in which the signal is developed from the Doppler shift of light reflected from a slowly moving target. Such an instrument has been successfully developed for far-field measurements of target materials. In this paper we will present recent theoretical analysis of the speckle statistics and the signal over noise ratio of the monostatic bidirectional reflectometer. Calculation is also compared with experimental results.
