Abstract

The purpose of this study is to explore novel monostatic ladar detection principles utilizing polarimetric Bidirectional Reflectance Distribution Function (BRDF) and single-pixel detection parameters. The depolarization of backscattered elliptical polarized light beams, from extended area space materials, was studied at different sample orientations. Specifically, the depolarization ratio for both linearly and circularly polarized light waves was estimated under quasimonostatic transceiver geometry. The experimental results indicate that space object materials exhibit distinct depolarization signatures, which provide enhanced discrimination capabilities. The outcome of this study would enhance the monostatic-ladar detection and discrimination capabilities.
